[poky] Parsing fails when a recipe is using distutils.bbclass

[Koen Kooi]

Hi,

I'm trying to build gnuradio using the meta-openembedded overlay which is causing me some problems with python-cheeta. When I have built python(-native), everything is fine, but on a build from scratch (hitting the pseudo redirect):

koen at dominion:/OE/tentacle$ MACHINE=beagleboard ./oebb.sh bitbake foo
Executing: MACHINE=beagleboard bitbake foo
Pseudo has not been built, building this first before the main build

This is after syncing the needed classes with OE: http://dominion.thruhere.net/git/cgit.cgi/yocto/log/?h=koen but I get a similar error when using an unpatched tree.

The cheetah recipe looks like this: http://dominion.thruhere.net/git/cgit.cgi/openembedded/tree/recipes/python/python-cheetah_2.4.4.bb?h=org.openembedded.dev

Does anyone have a clue why the yocto bitbake is trying to expand PYTHONDIR during parsing?

regards,

Koen
