I agree -- that could create issues (though will mostly work, I suppose)
But somehow the python.org build has managed to make a pythonw that IS a
proper executable:
ORRW-M-1275474:bin chris.barker$ pwd
/Library/Frameworks/Python.framework/Versions/2.7/bin
ORRW-M-1275474:bin chris.barker$ ls -l pythonw
lrwxr-xr-x 1 root wheel 8 Jul 16 2013 pythonw -> pythonw2
ORRW-M-1275474:bin chris.barker$ ls -l pythonw2
lrwxr-xr-x 1 root wheel 10 Jul 16 2013 pythonw2 -> pythonw2.7
ORRW-M-1275474:bin chris.barker$ ls -l pythonw2.7
-rwxr-xr-x 1 chris.barker admin 9180 May 13 2013 pythonw2.7
ORRW-M-1275474:bin chris.barker$ file pythonw2.7
pythonw2.7: Mach-O executable i386
(yes, ti works for 64 bit too -- this just happens to be what I have)
It would be nice if Anaconda would do it the same way.
