I tried installing mod_perl (2.03) on my Win XP Pro (SP3) system (using ppm and the theoryx5.uwinnipeg.ca repository). With perl58.dll and mod_perl.so added to http.conf, httpd (Apache 2.052) restarted correctly. But, if either PerlModule ModPerl::PerlRun or PerlModule ModPerl::Registry was added to httpd.conf, httpd start would fail.
After much trial and error, it appeared that Apache2::RequestUtil would not load because the corresponding RequestUtil.dll load failed. After looking at the imports in auto/Apache2/RequestUtil/RequestUtil.dll, it seemed that it tried to import the symbol modperl_pnotes which was not exported from the mod_perl.so downloaded by ppm. The MD5 hash for the downloaded mod_perl.so is 6ac2e66ed1271dd89d484ea3b0b3b62f. Was RequestUtil.dll built with a later version of mod_perl.so than is in the repository? Has anyone else seen this problem? Dan
