Thanks for the troubleshooting tips.
I went through and verified that mod_transform does call libxml2 (see
libxslt.so.1 => /usr/local/lib/libxslt.so.1 (0x4001f000)
libxml2.so.2 => /usr/local/lib/libxml2.so.2 (0x4004e000)
I also verified that the symbol existed
nm /usr/local/lib/libxml2.so |grep _xmlParser
In both cases, the values seem to be there. So I went ahead and ran the
mod_svn_view module, and it ran through fine. I then restarted Apache again,
and this time I got no error. Weird. Is there any sort of
recompilation/linking done to mod_transform in the mod_svn_view build
Either way, I am able to start Apache with both the mod_svn_view and
Thanks for the help!
