Development files normally have the postfix -devel
in Redhat/Fedora (but unfortunately sometimes without the lib prefix).
The package is called libpurple-devel
in Fedora 11 and I think that might be true for Redhat too. Try yum search purple
to search for packages.
Anyway, there seems to be no official python binding maintained by libpurple project yet, so you must probably download and compile the experimental binding on your own.
You can get the most recent version of the binding with the following command (the package subversion
must be installed for that):
svn co https://garage.maemo.org/svn/carman/trunk/python-purple/
After that you can change into the newly created python-purple/ directory and read the REAME file. I hope that helps :)
