Hi, I was trying to build 64-bit mod_perl but it failed because there was no 64-bit perl library. Same is true for Subversion modules. They need 64-bit version of the corresponding component libraries which are currently not available. Hence, not all the modules (listed below) which are part of 32-bit Apache will be there in 64-bit Apache.
Subversion modules:
mod_dav_svn.so
mod_authnz_svn.so
Perl module:
mod_perl.so
