yes, quite possibly. > Apache::Request: - > CGI : 3.05 > LWP : - > mod_perl : 1.9908, 1.9914, 1.9916 if you can (like there is no mod_perl 1.0 installation you care about) I would remove all Apache related things in your site_lib, including mod_perl.pm ModPerl/* Apache/* Apache2/* as well as /usr/local/apache2/modules/mod_perl.so. then 'make realclean' in your mod_perl-1.99_16 directory and start all over again. if 'make test' passes then you should be able to 'make install' and everything should be ok. if it's not, check to make sure that the mod_perl.so in your /usr/local/apache2/modules is the same as the one you'll find under your mod_perl build directory. sorry, I know that nuking everything and starting all over isn't exciting, or exactly useful in terms of help, but... --Geoff
