Matt,

thanks for the heads up. I made the patch and am trying to rebuild. Thanks!

Hi Eric,

Looks like this is known for non-framework builds of Python on OSX.

(We don't build it Framework-wise because it caused a bunch of

problems in the past and mainly only allowed usage of a few native

widgets.) Here is a patch you can apply and then rebuild Python with

to (possibly) get it to work:

Hello,

I know this is not a yt specific issue, however it involves an interaction

of the yt installed python and XSPEC. Maybe some of you on this list have

done an XSPEC install on Mac OS X (Lion in this case) and run into this. At

link time during the build of XSPEC, it gives the following error:

Undefined symbols for architecture x86_64:

"_environ", referenced from:

_initposix in libpython2.7.a(posixmodule.o)

ld: symbol(s) not found for architecture x86_64

Originally on my Mac, XSPEC tried to build 32-bit, and failed with python

linkages (since python is 64 bit in the yt install build). Once I went to

64-bit, this was the only remaining error. Does anyone have ideas?

Thanks!
