Nokogiri on Windows with Jruby?

Has anyone gotten nokogiri working on Windows?  I had to put the libxml and related dlls in my path, which makes sense, but now it says it can't find the calloc function.  I assume that's in the basic c runtime library.  But I did try putting msvcrt-ruby18.dll in my path, which I snarfed from my windows C Ruby install - but it didn't work.

Here's the stack trace:
