The old xauth beast again - Slackware

[Colin J. Raven]

Hi all!
I've RTFM'd...believe me, I've been reading posts for 2 days now on the
xauth issue.
The trouble is (AFAIK) no one has actually answered the question in
layman's terms:

"I try to start vncserver and get the error message; 
vncserver: couldn't find "xauth" on your PATH."

Now I read through the vncserver script carefully, but I'm stupid when
it comes to perl. This one however made me wonder if here might be the
answer:
$xauthorityFile = "$ENV{XAUTHORITY}" || "$ENV{HOME}/.Xauthority";
Should this be hacked to read something else?

BTW, doing a find on xauth yields nothing on my system (Slackware) so I
just dunno what to do. I'd happily add it to the path (although I read
posts that darkly hinted this was insecure) IF I could find the damn
thing.

Please someone, what do I do about the xauth error message? - in
beginner's language for pete's sake!!

Regards & Heartfelt TIA,
-Colin
