Remember.  Ultrix is not UNIX!  (yuck yuck)

First off, I'll assume you know about 32-char maximum, since you mention
SunOS already.  Thus, I presume you ran into the stupid stupid problem
that I did... that symlinks in the command name are *expanded* *within*
that 32-char limitation *only* under Ultrix!  Gack!  Under SunOS, for example,
you can:

	ln -s /some/humongously/long/path/name/to/somewhere /tmp/foo

and run a script that begins:

	#!/tmp/foo
	script here

but try to run the *same* thing on Ultrix, and you get something like:

/some/humongously/long/path/nam not found

Grrrrr.  Double grrrrrr.

Does this answer it?  Even if it doesn't, this message should make
others aware of such an awful problem.  I ran across it because I
wanted to symlink my /local/usr/bin on the VAXen to
/base/vax-ultrix3/local/usr/bin, and the path is a wee bit too long.
Had to shorten it to /base/vax-3/local/usr/bin, and even then I had to
make a symlink from tp to taintperl so that I could put
/local/usr/bin/tp in my scripts (for some "illegal" setuid scripts
that I have).

print "just another Perl hacker, a wee bit too long..."
