Whoa, now you are entering what I like to call the unknown zone.... for me I
try to read the error messages as best as I can and put the dll's its asking
for in the proper places. There is also a file with the extension
.immodules that I think is important in processes like this. For me its
located in the same directory as the .loaders file, but I have been using an
experimental medsphere installer. If I was you I would go on a hunt for
your libcroco, and patch the build and send it along upstream. Make sure
though that libcroco is cross platform, aka no improper PInvokes etc.
