However you can try the following:
perl Makefile.PL ... make t/TEST -conf perl -pi -e 's|Listen\s+(\d+)|Listen YOURHOSTNAME:$1|' t/conf/httpd.conf t/TEST cd ModPerl-Registry t/TEST -conf perl -pi -e 's|Listen\s+(\d+)|Listen YOURHOSTNAME:$1|' t/conf/httpd.conf t/TEST
replace YOURHOSTNAME with your hostname ;) may be localhost will do, I haven't played on Ipv6 system yet.
Localhost didn't work :)
