[SciPy-dev] no linalg module and failed check_integer test

I just installed scipy from svn and I am having some problems.  The
most vexing is that I can no longer load the linalg package, at least
I can't do anything with it.  For example:

Python 2.5 (r25:51918, Sep 19 2006, 08:49:13)
[GCC 4.0.1 (Apple Computer, Inc. build 5341)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import scipy
>>> scipy.pkgload('linalg')
>>> help(scipy.linalg)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'linalg'
>>> A = scipy.ones((10,10))
>>> scipy.linalg.eig(A)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'linalg'
>>>

I didn't notice any errors during the installation.  I know this isn't
a lot of information to go on, but does anyone know what the problem
is?

Secondly, and this might be related, when I run

scipy.test(1,10)

I get the error shown below.  Could this be the cause of my linalg problem?
Thanks in advance,
Jeremy
