[TxMt] problem with xml:tidy command: Symbol not found: _gzdopen

[Stephen Bannasch]

I'm getting this error message when running the command tidy from the 
XML bundle on any xml doc:

Errors: dyld: lazy symbol binding failed: Symbol not found: _gzdopen
   Referenced from: /opt/local/lib/libxml2.2.dylib
   Expected in: dynamic lookup

Here's a couple of questions:

1) How can I get access to the error above which appears in a yellow 
fading window in a location I can copy and paste.

2) How is the default path set for running textmate commands from 
bundles -- perhaps I can remove /opt from the path?

3) Anybody know what this error message means?

Thanks
