 %description devel
 Provides development headers for numa library calls

Please consider the missing Requires a bug that should be fixed in FC-6 and up -
it breaks builds.

Buildroot needs fixing:

The recommended values for the BuildRoot tag are (in descending order of
preference) :

%(mktemp -ud %{_tmppath}/%{name}-%{version}-%{release}-XXXXXX)
%{_tmppath}/%{name}-%{version}-%{release}-root-%(%{__id_u} -n)
%{_tmppath}/%{name}-%{version}-%{release}-root

Need to add to %files:

%doc README

you might also add CHANGES

Good:

- package meets naming guidelines
- license (LGPL/GPL) OK, matches source
- spec file legible, in am. english
- source matches upstream
- package compiles on devel (x86)
- no missing BR
- no unnecessary BR
- no locales
- not relocatable
- owns all directories that it creates
- no duplicate files
- permissions ok
- %clean ok
- macro use consistent
- code, not content
- no need for -docs
- nothing in %doc affects runtime
- no need for .desktop file
- no .la files
- post/postun ldconfig ok

Suggestion:

Why not:

 %prep
-%setup -q -c -a 0
-%patch1
-%patch2 -p1
+%setup -q
+%patch1 -p1
+%patch2 -p2

fixed in -3.fc8.  Thanks!

Looks like the License tag needs updating as per

You don't want %{dist} in the change log:

But I think that's about it...

dist has been removed from changelog.
