/Applications/hcm.app/Contents/MacOS/hcm: Mach-O 64-bit executable x86_64

But if I replace /Applications/hcm.app/Contents/MacOS/hcm with a symlink to
a wrapper shell script, hcm runs fine from the Applications menu.

It seems that gi.repository.Gtk applications are not packaged correctly by
pyinstaller and py2app.  Some Python modules require a little assistance to
be packaged up into a Mach-O executable neatly by such tools.  But it's
just not that important to me to have a Mach-O of my app.
