While rebuilding all the packages on my system after some filesystem corruptions, python-2.6.5-r3 and 3.1.2-r4 fail to build with the following error:
Code:
Failed to find the necessary bits to build these modules:
_tkinter           bsddb185           dl             
imageop            sunaudiodev                       
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


Failed to build these modules:
_socket            _ssl

I have tried rebuilding its immediate dependencies and it still fails to build. Anyone got any ideas?

Output from "emerge --info =dev-lang/python-2.6.5-r3": here
Full build log: here

Thanks

Reinstalled bluez (and its corrupted dependencies) and python is compiling fine now. Thanks :D

I will post here because this topic is very good referenced by google.(even if it's from 2010)

So, if you have old kernel or/and old gentoo and you want to install new portage you will have a dependency also new python(in my case it was python-3.3.2-r2)
If you receive an error telling you that something is wrong with _socket _ssl and the errors are :

Code:

/var/tmp/portage/dev-lang/python-3.3.2-r2/work/Python-3.3.2/Modules/socketmodule.c: In function âmakesockaddrâ:
/var/tmp/portage/dev-lang/python-3.3.2-r2/work/Python-3.3.2/Modules/socketmodule.c:1236: error: dereferencing pointer to incomplete type
/var/tmp/portage/dev-lang/python-3.3.2-r2/work/Python-3.3.2/Modules/socketmodule.c:1237: error: dereferencing pointer to incomplete type

Then you need to apply the fallowing patch
Code:

diff -r b3c2472c12a1 Modules/socketmodule.c
--- a/Modules/socketmodule.c   Wed Jan 22 22:24:46 2014 +1000

More about this patch you can find here: http://bugs.python.org/issue20065

In order to apply the patch you:
1) download the patch from : http://bugs.python.org/file33664/af_can_define.diff
2) Modify the ebuild by adding something like : epatch "${FILESDIR}/af_can_define.patch" after all the patches
3) And recreate the digest : ebuild python-3.3.2-r2.ebuild digest

I hope that will save a lot of time for people that are stuck with this error.
