Description of problem:
/usr/lib/im/leif/CannaLE.so dl's libcanna.so, but
iiimf-le-canna doesn't have a dependency on Canna.
Currently it is quite possible to install iiimf-le-canna
with the wrong version or no version of Canna installed.

Version-Release number of selected component (if applicable):
11_4-4

How reproducible:
everytime

Steps to Reproduce:
1. rpm -q --requires iiimf-le-canna-11_4-4 | grep canna
  
Actual results:
none

Expected results:
Canna = 3.7
libcanna.so.1.2

Additional info:
I recommend defining

  %define canna_ver 3.7

and then

  BuildRequires: Canna-devel = %{canna_ver}

and

  %package -n iiimf-le-canna
  Requires: Canna = %{canna_ver}
