Hmm, I've tested on RHEL 4 and FC4.  But I don't know which flavor of
RHEL I used.  I think it might be AS, not WS, but I honestly don't know.
Also, my build/test platform isn't fully up to date -- I build with the
oldest available s/w in order to protect myself from backwards-
incompatible library changes.

Neither.  That message is relatively normal and is perfectly safe to ignore.
The tainting is due to the fact that the Linux Developers don't consider
the IPL a "valid" open source license.
