Maybe. But I for one am happy for the diversion. A lot of mod-perl

unfortunately PERL_STACKED_HANDLERS used to be

about EVERYTHING except PERL_STACKED_HANDLERS.

I don't know if this is a problem w/ modperl or apache itself.

Thanks, Gerald! It might be a good idea as well to make the default log file
be auto-configured during build time (if it finds apache sources) to point to
embperl.log in whatever apache has configured as the log directory. Using /tmp

There must be a bug somewhere because I had EMBPERL_DEBUG = 0 and was getting
errors about not being able to write to /tmp/embperl.log.
This is with v 1.2b4 I believe so if this has changed recently that may be why
I got the errors.

If I understand you correctly, you don't want to use mod_perl, just
Perl.
If so, the easiest way to use perl is to dowload ActivePerl (free) from
Activestate website http://www.activestate.com/ActivePerl/download.htm
It comes with great documentation, install it as per documentation.

We're veering WAY off-topic here, but the fact is you can't guarantee
