Problems installing libxml

Hi, everyone,

I’m having trouble installing libxml-ruby and was hoping someone here
help. I’ve run into the same problem on both Mac OS X Tiger and Ubuntu
Dapper Drake (6.06 LTS). I’ve most recently tried installing on Dapper
where I installed Ruby 1.8.5 from source. I’ve tried both installing
gem for the latest stable release ( and also using the tarball
0.4.0pre01 (although the gem the Rakefile creates is called
libxml-ruby- Neither works.

Here’s what I get when I try to install the development release:

No definition for ruby_xml_html_parser_filename_get

Enclosing class/module ‘mXML’ for class Reader not known

Enclosing class/module ‘mXML’ for class Attribute not known

No definition for input_callbacks_register_input_callbacks

No definition for input_callbacks_add_scheme

No definition for input_callbacks_remove_scheme

Any suggestions?
