Installing libxml on osx as Gem

I’m trying to install libxml on osx as a gem (Ruby 1.8.2). Any ideas on
how to resolve these issues? (please see output below)

Thank you,
Nicholas

Hmm, find_header should be defined by mkmf, so I don’t understand what’s
going on there. Maybe it’s something to do with OSX - has anyone else
seen this?

Anyway, could you post up your ruby version? Also, the results of
running this:

$ ruby -rmkmf -e ‘find_header(“libxml/xmlversion.h”,
“/usr/include/libxml2”)’

Thanks,

Upgrading to 1.8.4 resolved this.
