I've just updatet Oort from CVS. When (require ...)'ing gnus-load it
stops with the error: Symbol's value as variable is void: lpr-command.
If I define lpr-command, the same is for lpr-switches.
When I define both prior to (require 'gnus-load), it works again.
The problem is in file mailcap.el, in the following strings:
(defvar mailcap-print-command
(mapconcat 'identity
(cons lpr-command
(if (stringp lpr-switches)
(list lpr-switches)
lpr-switches))
" ")
"Shell command (including switches) used to print Postscript files.")
Currently I can't find the XEmacs equivalent of lpr-command and
lpr-swithes (assuming, there're some), and would suggest checking for
these variables, if they're not bound, setting them to "lpr" and "". Can
anyone suggest a better way?

Forgot to mention:
1. Of course, this leads Gnus to fail with byte-compiling.
2. It's XEmacs 21.4.12 here.

I think it's slightly better to not pollute the global name-space. I've
added a boundp check instead. Does it work for you?

Strange, they're both bound in my version of XEmacs:
"21.4 (patch 6) \"Common Lisp\" XEmacs Lucid"
`lpr-switches' is even mentioned in the XEmacs manual (in the 'Hardcopy
Output' node).

Yes, thanks, it works OK.

I've finally guessed! =)) They're in XEmacs -- but probably in the
ps-print package, which I don't have here.

Installing the ps-print package would solve it, but it is not listed
in the requirements for running Gnus, so maybe we should work around
it. If you apply the following patch, does Gnus work? If more
workarounds are needed, perhaps the ps-print package should simply be
added to the prerequisites.

I didn't try it, because I've already updated the CVS tree -- and it
contains similar (if not really the same =) patch from Jesper Harder.
Gnus works with it.
