Try this trick:
http://perl.apache.org/guide/debug.html#Using_the_Perl_Trace
to figure out where it hangs:

sorry, I don't know what this does. Has he heard of apachectl?

I suggest to try harder to install 5.6.1 and most likely his problems 
will go away without wasting too much time on these issues. Try to seek 
help on the appropriate forums/news/mailing lists. There must be someone 
releasing the binary package.

that is probably a question for the modperl list, but the first answer you
would get will be upgrade to 5.6.1 first. Of course I don't discard the
possibility of a potential bug in mod_perl, but chances are very low, since
so many people are using Apache::Util/Template and there were no reports 
of any problems with loading.
