Can you join us over on enthought-dev? It's a more appropriate forum.

Can you double-check that the Pyrex that you can import is the version that you
think it is? One of the changes in 0.9.6 causes exactly this problem.

>>> from Pyrex.Compiler import Version
>>> Version.version
'0.9.5.1'

The tarballs you grabbed are experimental ones for people trying to package ETS
for Linux distributions. The people making them wanted to remove the namespace
package features, but it appears that they did so incompletely.

The tarballs that you want are here:

Alternately, we have a script that can check out the SVN for a given ETS package
and all of its dependencies.

  https://svn.enthought.com/svn/enthought/branches/ets_scripts_0.1

Install that like normal ("python setup.py install"). Then you will have a
script called "etsco":

$ cd ~/src
$ etsco enthought.mayavi

WARNING: YOUR CHECKOUT INCLUDES PROJECTS FROM SVN TAGS -- PLEASE BE CAREFUL WHEN
CHECKING IN CHANGES AS TAGS SHOULD NOT BE CHANGED!  You can svn copy a tag to a
 branch, then svn switch to that, and then check in your changes for a future
release.

Now, in enthought.mayavi_2.0.3a1/ you have all of the current SVN for
enthought.mayavi and everything from ETS that it needs.
