Turns out I lied. Recent git already has a better check:
if not hasattr(setuptools, "_distribute"):
Would you like me to roll a new release of MeshPy to make your packaging
easier?

To follow up on this: I think this is a good enough way. See here:
Python 2.6.5+ (release26-maint, Jul 6 2010, 14:48:45)
[GCC 4.4.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import setuptools
>>> setuptools.__file__
'/home/andreas/pool/lib/python2.6/site-packages/distribute-0.6.10-py2.6.egg/setuptools/__init__.pyc'
This is on recent Debian.

setting boundary conditions
by Islam El Salawi
Hi there,
I just succeeded in reading in a cgns mesh from icem in hedge, by converting its points and elements to the according format. Now I need to know how to assign boundary conditions. The geometry is a 3d dummy test cube, which siedelengths are 4 units. I want one face to be the inflow area, the adverse face should be assigned as outflow. The other four faces are walls, characterized as no slip boundaries.
Thanks
Islam

I agree with you, and this would be possible for Triangle. For TetGen, I
actually ship a patched version (and upstream doesn't like my patch), so
this would be more difficult. To compound the difficulty for Triangle:
the upstream package doesn't build a library by default. Given this
situation, shipping the libraries is IMO likely the easiest way.
