There is either a bug in Arch's packaging of glibc/rpcgen or it is upstream.
rpcgen was removed from glibc a while back and then was put back in when
libtirpc wasn't ready for use. Given this failure, after much investigation, it
was discovered that the rpcgen in glibc on arch searches for cpp in:
(2) /usr/ccs/lib/cp (really...?)
Neither of which are present on Arch any longer leading to the tdebase build
failure. To fix the problem all I did was create a symlink in the archroot for
/lib/cpp->/usr/bin/cpp. Now tdebase builds just fine.
I know the /lib/cpp link disappeared somewhere between June 4, 2012 and July
8, 2012 because tdebase was building fine on 6/4 and then failed beginning
With all the changes to glibc 2.16 I don't know if this missing link is an
arch packaging issue or upstream. Regardless, it is a problem that affects
packages relying on rpcgen.
