On my machine I see the following error after upgrading python-mode and subsequently invoking it:

Symbol's value as variable is void: py-python-command

I'm using an ~amd64 system with hardened profile and gcc-4.6.2 (although this should not make that much of a difference). Downgrading to python-mode-5.2.0 makes everything working fine.

I'm using emacs-23.3-r2.

Sorry, but I cannot reproduce this, so could you please provide a recipe how to reproduce the problem, starting with "emacs -q"?

Also, do you have any other Python related Emacs packages installed (like app-emacs/pymacs or dev-python/ipython)? What versions?

[Comment 2 Markus Walter 2011-11-23 14:01:54 UTC]

This always happens for me when using python-mode. So the recipe is quite short:

$ emacs -q
M-x python-mode

I have dev-python/ipython-0.10.2 installed, but not app-emacs/pymacs.

If I remove ipython the problem vanishes and on first look everything works fine again.

Does the following patch (from upstream) fix the proplem for you?

Yes this works.

Fixed in -r1. Thank you for reporting.
