blender2crystal export on mac

[Penwriter]

Hi, I'm sure this is answered somewhere else, but I can't seem to find it. I'm running on an intel iMac running osx 10.5. I've downloaded and installed CS1.2.1. My Blender is at 2.48a with python 2.5 and I installed the latest blender2crystal python scripts. Just as a proof of concept, I am trying to export the default (cube, light, camera) blender setup. When I try to run the export script, here is what shows up on the console:

Code:

Compiled with Python version 2.5.2.
 Checking for installed Python... got it!
 W:----------------------------------------------------
 W:ATTENTION: 4Suite not Found!! Using xml.dom.minidom.
 W:ATTENTION: Perfomance will be degraded, please install python-4suite.
 W:ATTENTION: You can download it from http://www.4suite.org/
 W:ATTENTION: or install for your favourite linux distribution.

What am I doing wrong, please?

I think you miss the Python XML support, generally solved by installing PyXML or 4Suite.
No idea which is the recommended/easier to install on Mac, but any of the two should do.
If one doesn't work, try the other.

Thanks for your response, Vincent. I'll look for PyXML and see what that does. I do have 4Suite installed, but for some reason, it isn't being recognized. I haven't been able to figure out why that is.

If 4Suite is installed in a custom location, you'd need to set PYTHONPATH (at least on Linux it's named like that) environment variable to point to that location.
