Problems installing py26-scipy -> gcc43

[Robert Wilson]

The following is on an iMac running Mac OS X 10.6.3.

As a result of trying to install py26-scipy @0.7.1 I need gcc43.  The
compilation was failing because of a conflict between the type of
pointer_t in /usr/include/mach/vm_types.h and that in the module.c
file.  I introduced the following change in module.c and the
compilation proceeded, but it is hard to be sure that it will work
correctly:

#define P_UNKNOWN 0
#define P_OTHER 1
#define P_NAMESPACE 2
#define P_COMPONENT 3
#define P_SYMBOL 4
#if 0
typedef enum
{
 P_UNKNOWN = 0, P_OTHER, P_NAMESPACE, P_COMPONENT, P_SYMBOL
}
pointer_t;
#endif

Having done this, it all compiled and I was able to install scipy, but  sys.path in python still showed the
original OS-X paths.  I set PYTHONPATH to /opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/:/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages
and could import scipy.  Running scipy.test(), however produced errors:

......
Ran 3488 tests in 41.445s

FAILED (KNOWNFAIL=4, SKIP=21, errors=3)
<nose.result.TextTestResult run=3488 errors=3 failures=0>


Before the 'fix", running "port  -d install gcc26" produced the following :

Any help would be appreciated.
