I am having a seg fault when I type help("modules"). I don't know if there are any other implications. I already reemerged python (this version) and ran python-updater. No success. Here is what happens: $ python Python 2.6.5 (release26-maint, Nov 9 2010, 03:26:26) [GCC 4.4.4] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> help("modules") Please wait a moment while I gather a list of all available modules... CXX is installed. The support files you need are in the PYTHON/etc/CXX directory. The include files are in the distutils include path already.

Try python -v ; help("modules") and see if its a specific library that crashes it.

What version of scipy? Please try rebuilding it

I wrote I already reemerged it. Anything > else I can do? Sorry, I somehow missed that you actually reemerged it. I just tried building scipy and tried with python 2.6.6 and python 2.7 - weren't able to reproduce. Next step will be backporting to 2.6.5. If you could try updating to 2.6.6 (in unstable), that would be helpful.

Has anyone in the sci herd been able to reproduce this? I'm at a loss here :(
i was able to replicate a while ago but it seems gone now. probably something fishy going on in the dlopen so i will close it for now, feel free to reopen
