[MacRuby-devel] hpricot and macruby?

[macruby at djc.net]

With:
MacRuby 0.10 (ruby 1.9.2) [universal-darwin10.0, x86_64]
and having done successfully:
macgem install hpricot ...

I get this when trying to use the actual gem:

dyld: lazy symbol binding failed: Symbol not found: _rb_enc_to_index
   Referenced from: 
/Library/Frameworks/MacRuby.framework/Versions/0.10/usr/lib/ruby/Gems/1.9.2/gems/hpricot-0.8.4/lib/fast_xs.bundle
   Expected in: flat namespace

is this a hpricot or macruby issue?
Any tips appreciated ... or do I give up, and attempt to convert this old 
script  to use: NSXMLDocument ?
(ruby 1.8.7 is core dumping, having its own problems, so I am hoping MacRuby 
is up to the task...)
