SPEC invalid.

1. Let's see the perl file itself:

Quoted:

use strict;                                   # core
use version;                                  # core
use FileHandle;                               # core
use Getopt::Long;                             # core
use File::Basename;                           # core
use Digest::file;                             # core
use Digest::SHA qw(sha256);                   # core
use Data::Dumper qw(Dumper);                  # core
use Term::ReadLine;                           # core
use Term::ANSIColor;                          # core
use Carp qw(longmess);                        # core
use Time::HiRes qw(gettimeofday tv_interval); # core
use POSIX;                   # core, required for unsafe signal handling
use Crypt::Rijndael;         # non-core, libcrypt-rijndael-perl on Ubuntu
use Sort::Naturally;         # non-core, libsort-naturally-perl on Ubuntu
use Term::ReadKey;           # non-core, libterm-readkey-perl on Ubuntu
use Term::ShellUI;           # non-core, libterm-shellui-perl on Ubuntu
                             #  - add Term::ReadLine::Gnu for cli history
use File::KeePass 0.03;      # non-core, libfile-keepass-perl on Ubuntu
                             #  - >=v0.03 needed due critical bug fixes

So, it needs a lot of dependencies. And you may ask, should I write it in the spec?

Then let's see back to your another spec:

http://fedorapeople.org/~delete/kpcli/perl-Term-ShellUI.spec

We can see a line:

Requires:       perl(:MODULE_COMPAT_%(eval "`perl -V:version`"; echo $version))

So this is the magic, when you add this as "Requires", RPM dependencies generator will look into the perl file and then automatically add requires when installing it. But sometimes it also ca make mistakes, so if RPM can't cover all dependencies during deps check, then you should add missing ones to the SPEC.

ALSO, Requires: perl-Term-ReadLine-Gnu should be corrected.

2. %description:

KeePass Command Line Interface (CLI) / interactive shell. 
Use this program to access and manage your KeePass 1.x or
 2.x databases from a Unix-like command line

You should add a dot at the end of these texts, and you shouldn't leave a space:

 2.x databases from a Unix-like command line

should be:

2.x databases from a Unix-like command line 

3. %install:

install -d %{buildroot}/%{_bindir}/
install -m 0755 %{name}-%{version}.pl %{buildroot}/%{_bindir}/%{name}

You didn't preserve the timestamp.

Suggestion:

mkdir %{buildroot}%{_bindir}/
install -pm0755 %{name}-%{version}.pl %{buildroot}%{_bindir}/%{name}

And, you can remove the common slash when writing such paths:

%{buildroot}%{_bindir}

As %{_bindir} eq /usr/bin, it already has it.

4. Hope you can add a %build section and write:

%build
# Nothing to build.

5. We have standard of Source0 URL, you can find a direct link when counting 5 in the download page:

http://downloads.sourceforge.net/project/kpcli/kpcli-2.3.pl?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fkpcli%2Ffiles%2F%3Fsource%3Dnavbar&ts=1377742463&use_mirror=superb-dca2

So it should be:

http://downloads.sourceforge.net/project/%{name}/%{name}-%{version}.pl

6. Keep your spec beautiful by reordering:

Name:      kpcli	
Version:   2.3
Release:   1%{?dist}
Summary:   KeePass Command Line Interface (CLI) / interactive shell
License:   (GPL+ or Artistic) and (GPLv2+ or Artistic) and MIT and Public Domain and UCD	
BuildArch: noarch
URL:       http://kpcli.sourceforge.net/	
Source0:   http://downloads.sourceforge.net/project/%{name}/%{name}-%{version}.pl

I updated the .spec file according to your suggestions. Let me know if you see something else wrong. 

SPEC: http://fedorapeople.org/~delete/kpcli/kpcli.spec
SRPM: http://fedorapeople.org/~delete/kpcli/kpcli-2.3-2.fc20.src.rpm

Thank you!

I updated the .spec file again, to fix a license problem described on BZ#1002321
