Check the full path of the perl executable with "which perl". Yes, if
you compiled perl from source, the default install location is
/usr/local/bin/ . If you did "rpm -Uvh perl-5.8.6.redhat9.rpm" and
you're still getting 5.8.0 from perl -v, something weird is happening.

This is what I'd recommend too. Maintaining an RPM-based distro is a
freaking PITA, and Redhat 9's been EOLed for over a year now.

Also you may want to Google "rute user tutorial" and look in
/usr/share/doc/howto/ for the Win95-to-Linux or Dos-to-Linux HOWTOs.

Er, not quite. NFS is done partially in kernelspace for some
$DIETY-damned reason. This makes it more difficult than it should be to
get NFS up, as you have to have NFS server support built in to the
kernel or available as a module.

There are also version mismatch problems; if you have an old client that
only groks NFSv2, and you set your server up with NFSv3 support, "mount
-t nfs machine:/blah /mnt/blah" can hang indefinitely. Not to mention
the endemic file locking problems. Samba has more overhead, but I've
had fewer problems with Samba than I've had with NFS, and I've been
using Samba every day for the last 5 years and NFS only 4 times in that
period.

"Mainframe" typically refers to one of those big IBM dinosaurs with
raised flooring and boatloads of I/O, not a 36-pound box with 9 VME
boards in it. Jargon namespace collision--sigh.

Yes, but how many FPS in RTCW does a "VME mainframe" get? :-]
