[rt-devel] RT3/Apache2/Mod_Perl2 (Global $r object is not available.)

[Brook Schofield]

I saw a posting by alex at porous.de in March this year - regarding the 
error message:


# /usr/local/apache2/bin/apachectl start

this is a change in behaviour between Mod_Perl 1.99_08 and 1.99_09 
(I've been using 1.99_07). I don't know whether this has gone away in 
later versions of HTML::Mason (I'm still using 1.17 rather than 1.20) 
but I needed to add the following to /opt/rt3/bin/webmux.pl to get 
everything working. I don't know what changes need to be made so this 
can be more universally applied to Mod_Perl 1 and Mod_Perl 2 instances.

# diff -c bin/webmux.pl /opt/rt3/bin/webmux.pl | more
