I'm not familiar with Mason (in any form) or with RT, but it'd be interesting 
(and probably useful :-) to see the actual error messages in your 
httpd-error.log (or whatever yours is called).  When apache fails to start, 
it's usually pretty good about saying why (though finding the root problem can 
  sometimes be a pain. :-)  I would expect some sort of error message from 
perl itself about can't find the module and it giving an @INC, and none of 
those paths listed contains the RT::Mason, which would indicate it's installed 
in the wrong place (or the @INC doesn't have the right entries).  Of course, 
it could be something else. :-)

You could also ask on the DFW Perl Mongers list (dfw-pm at gamma.hyperusa.com) as 
there are some pretty good web/perl people there.
