Thanks for your persistence in this thread. I've just spent a half hour playing
around with your suggestions. Yes, the file man.config can be seeing by a regular
user. After running with the strace option several times, the best I can tell is the
MANPATH fields are not being read from the man.config file. I can rearrange the
search order MANSECT and those changes are reflected in the created man.log file, but
changes to MANPATH don't seem to make any difference. I'm not seeing any references
to this in google searches -- don't know if that means anything though. It's a bit
long, but I'm including the results of "strace -oman.log man man" at the end of this
post.
Cheers,
Gary
