It seems that i was barking up the wrong tree; While trying to build trinity-kdebase with the PKBUILD provided i ran into this: [ 37%] Generating mount_xdr.c cd /home/calvin/builds/trinity/trinity-kdebase/src/kdebase/kioslave/nfs && rpcgen -c -o mount_xdr.c /home/calvin/builds/trinity/trinity-kdebase/src/kdebase/kioslave/nfs/mount.x file `mount_xdr.c' already exists and may be overwritten make[2]: *** [kioslave/nfs/mount_xdr.c] Error 1 make[2]: Leaving directory `/home/calvin/builds/trinity/trinity-kdebase/src/kdebase' make[1]: *** [kioslave/nfs/CMakeFiles/kio_nfs-module.dir/all] Error 2 make[1]: *** Waiting for unfinished jobs.... It appears that mount_xdr already exists (obviously) rpcgen is attempting to over write it, and so Make gives an error? If anyone could reproduce this that would be helpful, i am at a complete loss.
