Yes, 2.7 is a dev branch which normally lasts for quit some time, 
however this time round they are hoping to move to 2.8 pretty quickly, I 
believe before the end of the year.

That is good news.

A problem I don't understand with matplotlib. This used to work, until I 
upgraded. Now running 

dev-lang/python-2.4.3-r4
dev-python/numpy-1.0
dev-python/matplotlib-0.87.7
sci-libs/scipy-0.5.1-r1

on a Gentoo Linux system :

2.6.16-gentoo-r3
AMD Athlon 64 X2 3800+

Among other things. ;)

I hope not.  I am guessing that wxPython is like the linux kernel, so
2.7 is a dev branch.

The native interface was  added for high speed blitting/animation.  A
while back we talked about and agreed on trying to remove the native
interfaces for gtk and wxpython to avoid these compilation headaches.
This was after having decent success with pure python approaches for
qt3 and qt4.  We are sticking with the unicode wxpython build for the
remainder of 0.87.x to avoid more confusion.  Ideally 0.88 will have
the pure python blitting implementations.
