[rt-users] 2.1.42 woes: undefined $ah in webmux.pl

[Patrick YU]

Hello all.

I'm trying to set up version 2.1.42 and the initial to the web UI caused 
the following Apache log:

Constant subroutine CGI::XHTML_DTD redefined at 
/Library/Perl/constant.pm line 108.
[Sun Oct 27 11:49:19 2002] [notice] Apache/1.3.26 (Darwin) mod_perl/1.27 
configured -- resuming normal operations
[Sun Oct 27 11:49:19 2002] [notice] Accept mutex: flock (Default: flock)
[Sun Oct 27 11:49:33 2002] [error] Can't call method "handle_request" on 
an undefined value at /usr/local/rt3/bin/webmux.pl line 88.

Any advise on how to proceed ?  I've determined that the $ah handler 
wasn't created / defined in webmux.pl.  The RT log file doesn't have 
anything after changing log level to 'debug'.

Configuration:
Mac OS X 10.1.5
Mason 1.10
mod_perl 1.27

thanks in advance,

Patrick
