nokogiri 1.6.1 not working with ruby 2.0 and mavericks

[David Byron]

I thought for sure now that libxml2 and libxslt are packaged with nokogiri that this problem (and http://nokogiri.org/tutorials/installing_nokogiri.html, http://dreamconception.com/tech/fix-nokogiri-install-issue-on-mac-os-x-10-9/ and https://github.com/sparklemotion/nokogiri/issues/742) was a thing of the past.  But, here I am, unable to get nokogiri to work.  This same code worked on an old machine of mine, and on a coworkers...so I think I'm dealing with an installation issue, but at this point I'm not sure.

Here are the details that I think are relevant:

$ bundle exec nokogiri -v

Here's a snippet from the dynamic library info from invoking the previous command with DYLD_PRINT_LIBRARIES=1:

And just in case:

$ brew list libxml2

Error: No such keg: /usr/local/Cellar/libxml2

$ brew list libxslt

Error: No such keg: /usr/local/Cellar/libxslt

I would be most grateful if someone could take a look and give me a hand.  If there is more info about my system I need to provide to work this out, please let me know.

Thanks much.

If it's somehow interesting, the libxml test program here: http://xmlsoft.org/examples/xpath1.c, compiles, links and runs fine:

$ gcc xpath1.c -I ~/.rvm/gems/ruby-2.0.0-p247/gems/nokogiri-1.6.1/ports/x86_64-apple-darwin13.1.0/libxml2/2.8.0/include/libxml2/ -L ~/.rvm/gems/ruby-2.0.0-p247/gems/nokogiri-1.6.1/ports/x86_64-apple-darwin13.1.0/libxml2/2.8.0/lib -lxml2

$ ./a.out test.xml "//soap_body"

where test.xml contains the same thing embedded in the ruby example I attached before:

<soap_body>

  <resource_id>custom_resource_id</resource_id>

</soap_body>

This tells me that the libxml2 that nokogiri uses is working properly.  Does this light a lightbulb for someone as to what's going on?

Thanks much.
