[Pyobjc-dev] Three issues with PyObjC under Snow Leopard

[David E. <dav...@gm...>]

(1) `http://pyobjc.sourceforge.net/downloads.html tells me that I can
update my pyobjc (currently the one that came with the Snow Leopard
install DVD) to 2.2b1 with the command line "easy_install
pyobjc=2.2b1". But when I try it I get the error message "error: Not a
URL, existing file, or requirement spec: 'pyobjc=2.2b1'". Are the
update instructions misleading or do I have a misconfiguration
somewhere?

(2) I have some apps I wrote using pyobjc under Leopard that broke
when I moved to Snow Leopard. The simplest is the one in
http://www.ics.uci.edu/~eppstein/LaTeX_Unicodifier.dmg.gz (that's the
app bundle but because it's Python the source is inside, and is quite
short). I don't want to ask anyone to debug my code for me, but I'm at
a bit of a loss: when I run it (either the app as I built it for 10.5,
or the same xcode project recompiled for a 10.6 intel target) I get a
mysterious message "10/4/09 8:28:13 PM	LaTeX Unicodifier[13914]	<type
'exceptions.TypeError'>: Need 0 arguments, got 1" on the console and
it doesn't work: the UI appears, cmd-Q quits, but the actual app
that's supposed to be running the UI isn't there. I imagine that
somewhere there's a method that needs a signature and doesn't have
one, or something simple like that, but I can't seem to figure out how
to get xcode to show me who's raising the uncaught exception...

(3) In an attempt to get around (2), I tried making a setup.py
following the example of
http://pyobjc.sourceforge.net/examples/pyobjc-framework-Cocoa/AppKit/CocoaBindings/CurrencyConvBinding/source--setup.py.html
in order to create an app using py2app instead of xcode. But this,
too, fails, with an error message
...
creating build/bdist.macosx-10.6-universal/python2.6-standalone/app/lib-dynload
creating build/bdist.macosx-10.6-universal/python2.6-standalone/app/Frameworks
error: Multiple targets not currently supported

Is there some parameter I need to set to get py2app to work or is this
also irredeemably broken?
