Hi, everyone,

I’m having trouble installing libxml-ruby and was hoping someone here  
could  
help. I’ve run into the same problem on both Mac OS X Tiger and Ubuntu  
Linux  
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  
the  
gem for the latest stable release (0.3.8.4) and also using the tarball  
for  
0.4.0pre01 (although the gem the Rakefile creates is called  
libxml-ruby-0.3.9.1.gem). 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?

Thanks!
