What tests did you run to determine that Apache/mod_perl is running  
happily?
If it was serving the test script through a mod_perl interface, the  
GATEWAY_INTERFACE environment variable should have indicated CGI-Perl.
That's what it says in all the Apache/mod_perl combos we know of.
It could well be that Apache is installed correctly with mod_perl, but  
various ScriptAlias directives are conflicting or preventing things in  
/OME/perl2 from executing via the mod_perl gateway.  There's apparently  
a conflicting ScriptAlias directive for omeis in your installation.   
OMEIS doesn't need mod_perl, but this is a strange error nonetheless.

Copy the test script out of the log file and save it as a file wherever  
your ScriptAlias is configured to go through mod_perl.  Then do a GET  
for this script from your browser.  You should see all the environment  
variables available to the script.  There has to be some indication  
there that its running via mod_perl.  If so, please let us know what  
those are.  If not, there's a problem with your ScriptAlias directives  
and/or the mod_perl installation.  The actual OME web server (serve.pl)  
should be in the same directory as your working test-script.
