[CLUE-Tech] help with GNU mailman - displaying jibberish

[Dan Harris]

I've been running GNU's mailman on a Debian (woody) server for a year or 
so.  I'm happy to say I haven't needed to touch the admin interface once 
since I originally set it up.  However, the need has come about for me 
to do it and I'm running into some very strange problems.  It looks like 
when apache ( 1.3.26 + mod_perl ) tries to exec one of the cgi programs, 
it shows whats at the following URL ( it's a bunch of garbage ascii ):

http://coronasolutions.com/cgi-bin/mailman/admin

However, when I run them from command-line ( su'd ), they appear to spit 
out the correct HTML to stdout. 

The 'admin' executable looks like this:

-rwxr-sr-x    1 root     list         5584 Sep 18  2002 admin

and 'ldd' output looks like this:

libc.so.6 => /lib/libc.so.6 (0x40019000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

I wonder if something happened during a software update that broke it?  
Is this a suid problem?  I'm confused..

Thanks for any help.
