[SciPy-user] Mayavi2 installation woes (OS X 10.4.11, Python 2.5)

[William Henney]

Hi list,

I have been trying to install MayaVi2 on an intel Mac running 10.4.11, but I am
running into a brick wall. 

I have been trying to follow the instructions I have found in various threads on
this list and at https://svn.enthought.com/enthought/wiki/IntelMacPython25. I
have managed to install all the dependencies (vtk, pyrex, wxpython, etc) but I
just can't get the enthought.traits package to build. 

I have tried the versions from the SVN repo and also the tar balls from
http://code.enthought.com/downloads/source/ets2.6/ but I always get the error
when building enthought.traits:

TypeError: swig_sources() takes exactly 3 arguments (2 given)

An example of a full stack trace is given below. It seems that the problem has
something to do with setuptools, and possibly with pyrex. I was initially using
setuptools 0.6c7 and Pyrex 0.9.6.4, but after reading negative comments about
0.9.6, I downgraded to 0.9.5.1a, although this makes no difference. 

I have also tried using the latest development version of setuptools
(0.7a1dev-r58661), but this doesn't work at all due to problems with "Namespace
Packages" (with 0.6 these just give a warning, as seen in the output below). 

Does anyone have any idea how to solve this?

Cheers

Will Henney
