Thank you! Can you update the readme file and send me a pull request?

The Readme says that you don't need to worry about 32 vs 64-bit mode on OS X Lion. This is incorrect. If the user runs it in 64-bit mode, WX gives an error (and this is with the Carbon version):

python ./pronterface.py
WX is not installed. This program requires WX to run.
Traceback (most recent call last):

If the following is used and pronterface is run again, the UI comes up:

export VERSIONER_PYTHON_PREFER_32_BIT=yes

Fixed.

I am also having this issue running OS X Lion, Apple's Python 2.7.2, wxPython 2.9.2.4 carbon. Typing this in terminal: export VERSIONER_PYTHON_PREFER_32_BIT=yes doesn't seem to fix anything. Thanks a lot for your help!

edit- I found a workaround. If I load it using: $ python2.7-32 pronterface.py It works fine.

I've had similar problems with the same error codes on the following system:

Mac OS X 10.6.8

export VERSIONER_PYTHON_PREFER_32_BIT=yes
instead of defaults write com.apple.versioner.python Prefer-32-Bit -bool yes
solved my issues
