Fwd: scipy 32 bit tests

I also have a report from Fernando about failures on 32bit Linux.

Hey,

on 32 bit ubuntu, we get for scipy a bunch of these:

======================================================================
ERROR: test_var_in (test_wx_spec.TestWxConverter)
----------------------------------------------------------------------
Traceback (most recent call last):
 File "/home/fperez/usr/opt/lib/python2.5/site-packages/scipy/weave/tests/test_wx_spec.py",
line 31, in setUp
   self.s = wx_spec.wx_converter()

   common_base_converter.__init__(self)

   cxxflags = get_wxconfig('cxxflags')
 File "/home/fperez/usr/opt/lib/python2.5/site-packages/scipy/weave/wx_spec.py",
line 32, in get_wxconfig
   raise RuntimeError, msg
RuntimeError: wx-config failed. Impossible to learn wxPython settings

it would be good to skip them gracefully rather than erroring out, so
we get less noise.

Some of:

======================================================================
FAIL: test whether all methods converge

Traceback (most recent call last):

======================================================================
FAIL: test whether all methods accept a preconditioner
----------------------------------------------------------------------
Traceback (most recent call last):
 File "/home/fperez/usr/opt/lib/python2.5/site-packages/scipy/sparse/linalg/isolve/tests/test_iterative.py",
line 111, in test_precond

line 180, in assert_equal

AssertionError:

 DESIRED: 0

These two appear like real failures

So I think on 32 bit we just need to worry about the two failures
above, and hopefully handle the wx stuff more gracefully.

cheers,
