Mike,

This is presumably your problem.   Normally MapServer when run as a cgi-bin
is run with the permissions of the "nobody" account or some other low
permission account.  It gets a rather minimal environment and most definately
does not get the environment of your normal user account.

There are various ways of setting environment variables for cgi-bin programs.
You can use the SetEnv directive in the apache configuration file, or create
a "cover script" for mapserv which sets appropriate environment variable.

So many FAQs ... so little time.

Best regards,
