It looks like it maybe failing to load libxml2.  try running "ldd" on
the mod_transform.so lib (ldd /path/to/mod_transform.so) and make sure
it's linked to libxml2.  Or try preloading libxml2 in the apache
configuration by putting this configuration line before the LoadModule
line for mod_transform.so

LoadFile /path/to/libxml2.so

also run the "nm" program on your libxml2.so and make sure it actually
has that symbol.

that particular error can be ignored, it's a libtool warning because
it's expecting a standard library, not a module.
