Description Michele Alzetta 2004-01-31 02:33:44 UTC
The long and short of all the problems I've been having lately seems to be this: python 2.3.3 gets built, but it's modules don't get built correctly, which is why python doesn't work and portage and .... etc. etc. 

I tried using mcpu=athlon-xp and -O2 instead of -O3 but the problem doesn't change.
I wander if it is the fault of the new glibc ?

These are the error messages I get in build:

unning build
running build_ext
building 'struct' extension

*** WARNING: importing extension "struct" failed with exceptions.AttributeError: 'module' object has no attribute 'load_dynamic'

A quick google reveals a similar problem with python 2.3.3 on a totally different architecture:

i can't see that their patches are relevant to whats happening on linux though. their patch adds -belf which isn't relevant with linux at all.

there's some other underlying problem here, especially as this is the first report i've seen of this kinda. does python-2.2 work fine for you?

please reopen if you have more info
