Thanks, that seems to have worked.  I added "/usr/local/bin" to the  
PATH in the preferences Environment panel in Komodo.  Then in  
preferences I went into the Python pane and changed my selected  
interpreter from "/usr/bin/pythonw" to the now available "/usr/local/ 
bin/pythonw".

Thanks again,

Jake
