I finally got around to install PearPC and OS/X on my laptop. Here is how I got Mattricks running:

How to install Mattricks on Mac OS/X (tested on OS/X 10.3.5)

* Download the Mattricks source:

Version 0.7 Release candidate 2: http://www.lysator.liu.se/mattricks/files/Mattricks-0.7_rc2.tar.gz

or

Latest CVS-version: http://cvs.lysator.liu.se/viewcvs/viewcvs.cgi/Mattricks.tar.gz?root=mattrick...

Put it in your home directory, open a terminal and do the following:

mkdir Mattricks cd Mattricks tar xf Mattrickssourcefile.tar

* Download wxPython for Mac:

Go to: http://prdownloads.sourceforge.net/wxpython/wxPythonOSX-2.4.2.4-Py2.3/panthe...

Select a suitable server and download wxPython.

In the disk image double.click on wxPythonOSX.pkg (not wxPythonOSX-devel.pkg) and follow the instructions to install.

* Download pyXML

Get the following file: http://undefined.org/python/pimp/PyXML-0.8.3.darwin-7.0.0-Power_Macintosh.ta...

Copy it to your home directory

In the shell window type:

cd / tar xf ~/PyXML-0.8.3.darwin-7.0.0-Power_Macintosh.tar

* Download py-bsddb

Get: http://undefined.org/python/pimp/bsddb3-4.1.6.darwin-7.0.0-Power_Macintosh.t...

Copy it to your home directory

Type:

cd /System tar xf ~/bsddb3-4.1.6.darwin-7.0.0-Power_Macintosh.tar

* Run Mattricks

type: cd ~/Mattricks/Mattricks-0.7_rc2

(Different directory for the CVS)

Then type (to finally start Mattricks): pythonw mattricks.py gui

Login with your username and password and wait until 30 or so files are downloaded (many of which are transfer history files)

Hopefully you are now able to run Mattricks on your OS/X computer and hopefully it was worth the hassle.
