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.
