The system does not symlink /usr/bin/cpp to /lib/cpp anymore which breaks the CDE compile. As root:
ln -s /usr/bin/cpp /lib/cpp
You must make this symlink before you compile or you won't get far.
At this point, go to the Compiling section on the [LinuxBuild] page, and continue from there.

There is a PKGBUILD in the AUR which may work for you. After the change to systemd the correct procedure for setting up rpcbind is to edit /etc/conf.d/rpcbind and change the line:
RPCBIND_ARGS=""
to:
RPCBIND_ARGS="-i"
As of CDE release 2.2.4a this step is no longer required.
Package
rpcsvc-proto
is required for rpcgen(1) command.PKGBUILD for 2.5.0
