Hi Who.
I think I know what your problem is. First, if you are using the same 
groff distribution I am (from virtunix), it is not built on top of the 
cygnus environment. As a result, it understands neither the cygnus

//d/dir/file

form of pathnames including drives nor (more importantly) paths defined 
partially by "mount". For example, I did this:

mount C:/crypto/pgp/doc /pgpdoc

From bash, I could cat /pgpdoc/BLURB.TXT fine. But when I tried feeding 
that same pathname into troff, it couldn't find the file.

I have the groff tools installed where the README.NT file says to put 
them. This means that the tmac directory, for example is 
/usr/local/share/groff/tmac and the font directory is
/usr/local/share/groff/font.
Just for fun, I renamed /usr/local/share to /usr/local/snare (and tmac 
to umac). Sure enough, when I tried running troff, I got your error 
message. then I defined environment variables like this (under bash):
export GROFF_FONT_PATH=/usr/local/snare/groff/font
export GROFF_TMAC_PATH=/usr/local/snare/groff/umac
That made everything work fine again. Incidently, just the TMAC part 
wasn't enough, so I think your error message means it can't find the 
font dir.

Moral: With the virtunix groff, don't rely on your mounts when you 
define the GROFF environment variables (or for anything else).

A cygnus-based groff would presumably put an end to this nonsense. Does 
anyone have one?
