Subject: Nokogiri on JRuby using OSX 10.5 and Mac Ports

I'm testing some code that uses Nokogiri under JRuby using rvm.
I have a fresh rvm install of JRuby, Nokogiri 1.4.3.1-java,
and the MacPorts 1.1.26_0 version of libxslt, which provides
/opt/local/lib/libexslt.dylib (i.e. everthing is up-to-date
except OSX)

I'm getting this stack trace:

~/.rvm/rubies/jruby-1.5.3/lib/ruby/site_ruby/shared/ffi/ffi.rb:112:in `create_invoker': Function 'xmlSchemaValidateFile' not found in [libexslt.dylib] (FFI::NotFoundError)

Googling yields no answers. Any thoughts on the cause or the fix?
