Yes, you will note that there is an appropriate LoadModule statement for 
that module and that of course if the AddHandler weren't being used then 
you would see the script source not get an error.

Yes, I'm aware of that, thanks.

temp:~# ls -l /home/ken/public_html/cgi-bin/            
total 16
-rwxr-xr-x    1 ken      www-data       75 Sep 16 09:56 bash.cgi
-rwxr-xr-x    1 ken      www-data     4861 Sep 16 14:07 cchello.cgi
-rwxr-x---    1 ken      www-data      139 Sep 13 16:02 quick.cgi

and note that the source code of the bash.cgi script is below in my 
original message, it is all of four lines, nothing more than echo 
statements.  You will note that there is now a compiled CGI there as well 
now (cchello.cgi) and it doesn't work either (along with the python one 
quick.cgi).  You will also note below if you look carefully that all 3 of 
these scripts are also in system-wide cgi-bin:

temp:~# ls -l /usr/lib/cgi-bin/
total 20
-rwxr-xr-x    1 root     root           75 Sep 16 09:49 bash.cgi
-rwxr-xr-x    1 root     root         4861 Sep 16 14:07 cchello.cgi
-rwxr-xr-x    1 root     root          139 Sep 13 16:04 quick.cgi

and work perfectly fine there.  You may not have noticed but I provided 
confirmation using md5sum below that the bash.cgi scripts in both locations 
are identical.

I will be hanging out in #apache on OPN (freenode) most of the day between 
say now and about 22:20 UTC.  If anyone would like to accost me there and 
point out my stupidity I would welcome it.
