Thanks for the ideas. No, Progress does not have it's own libraries, and
LD_LIBRARY_PATH is not set in any user's environment, including root, and
/etc/ld.so.conf is the same as other servers...
/usr/X11R6/lib
/usr/lib/mysql
Of interest: although root is running a bash now, it cannot invoke another
one.
And perhaps another clue: running "strace basename" on both machine that
fails and another FC3 server that works fine...

Perhaps someone that better understand the startup initialization process can read
something into that.
It looks like on the failed machine a normal user strace looks identical to the root
user. It does seem odd that when normal user runs "strace basename" on the failed
machine they do NOT get the usage output, but on the working machine they do.
