I've done a bit of work to use mod-caml with apache 2.2 . I've uploaded everything on the debian gforge website alioth.

to recompile the package you can get it via svn

Then you can compile the package with svn-buildpackage.

I've also wrote a small patch to recursively load dependent modules. I attached a simple loader module that is partially a rip-off of some GPL code I found on the net.
