Thanks for the hint. I'll try to get cx_freeze to bundle up other
shared libraries it may not be bundling such as qtcanvas, qtext, qtui,

I'll post back the results to help other poor souls like me.

Well I managed to get rid of the undefined symbol message by copying
all qt libs to the freeze directory, the problem is that now the

Hi Peter. Thank you for this warning. I'll document this in the code. I
plan on importing only from dependentpackage for portability. Also, much
in the framework relies upon it. This approach is primarily for
