Not high on the priority list. It would be nice if the GMPC-LIRC plugin were built along with all the other plugins. Right now I have to build it by hand. It's not a big deal, just a little inconvenient.
I am waiting for the Fedora 11 release before upgrading gmpc to the latest version and in the latest version I have prepared the lirc plugin is already included. So this will be fixed in a few weeks.
gmpc (0.18.0) in Fedora 11 should be compiled with lirc support now.
