Craig,

You may need to take this up with whoever you got the rpms from, as they
may not have packaged the datum shift files.

One work around is to install PROJ.4 from scratch in /usr/local from the
source.  Make sure you download and "overlay" the proj-datumgrid-1.3.zip
over your proj tree before configuring and building.  Once installed you
should have PROJ.4 in /usr/local, and some data files in
/usr/local/share/proj.  If they aren't getting used by default, set
the PROJ_LIB environment variable to point to that directory.
