[GRASS-dev] OSX Snow Leopard problem with python

After some tinkering, I found that the utils.reexec_with_pythonw() is  
not working.  I was able to manually run the GUI by commenting the  
utils.reexec_with_pythonw() lines in wxgui.py and menuform.py and  
starting the gui with

pythonw "$GISBASE/etc/wxpython/wxgui.py"

"We are at war with them. Neither in hatred nor revenge and with no  
particular pleasure I shall kill every ___ I can until the war is  
over. That is my duty."

"Don't you even hate 'em?"

"What good would it do if I did? If all the many millions of people of  
the allied nations devoted an entire year exclusively to hating the  
____ it wouldn't kill one ___ nor shorten the war one day."

<Ha, ha> "And it might give 'em all stomach ulcers."
