well, after a long time of compiling perl modules from cpan and failing on many differeing things, I found some useful RPM's which made things easier...
I downloaded and installed (in order or installation):-
After this I had one last problem. gimp-perl-1.2.5-1 only works with gimp 1.2, not gimp 2.0 which I had installed on my machine. This is cause gimp 2.0 is newly released so an RPM for gimp-perl 2.0 hasn't been made yet. There are sources for it i think (Gimp-2.0pre2), but I couldn't compile it properly for my machine.
So I removed gimp 2.0, and re-installed gimp-1.2.5-1. After this, I could write Perl code, and make use of all the gimp functions I wanted. yay.
thanks for the help j-ray, but I guess im not quite clever enough to compile perl modules properly... It definately kept me busy!!
