2.7 is currently holding at alpha2.  The 2.7 release schedule[1] shows 
that 2.7 final is due in June, and even if it's on time, it could be 
months before most software is ready for 2.7 and even longer before 
anything actually *needs* it.  I doubt most distros will make it the 
default 2.x version until 2011, so I still think 2.6 is the way to go 
right now.

Fair enough, especially as 2.7 is due to be the last version of the 2.x 
series.

You are correct that binutils becomes a dependency of python.  What I 
meant to say is that, e.g. as is done in PyOpenGL, 
ctypes.util.find_library('GL') will require /usr/lib/libGL.dll.a to be 
installed, meaning that libGL-devel (which already requires: libGL1) 
will be in python-opengl's requires:.  I understand this might sound 
strange at first, but if you look at the Linux code in ctypes/util.py, 
not only do you need the -devel package and binutils, but gcc (!) as well.

If the binutils dependency bothers you for python as a whole, you could 
always split out python-ctypes into a separate binary package.  You will 
see that my .cygport files do that for the test modules (as they are 
generally not needed for normal operation), Tkinter (as the Ports 
version uses *NIX/X11 Tcl/Tk, which adds several deps not needed by the 
rest of Python), and Idle (which depends on Tkinter).
