>Description:
Installation of lang/python26 fails because _ssl.so was not built.

*** WARNING: renaming "_ssl" since importing it failed: build/lib.linux-i686-2.6/_ssl.so: undefined symbol: SSLv2_method

Failed to find the necessary bits to build these modules:
_tkinter           gdbm               linuxaudiodev   
ossaudiodev        sunaudiodev                        
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


Failed to build these modules:
_ssl                                                  
=================

It seems Ubuntu version of openssl does not have a SSLv2_method.
http://stackoverflow.com/questions/8206546/undefined-symbol-sslv2-method

>How-To-Repeat:
bmake install
in
lang/python26 on Linux with no SSLv2_method in openssl.
>Fix:
I applied three local patches to remove SSLv2_method from Python. It
is not a patch proposal just an illustration.
