[SciPy-user] Installation problems Mac OS X 10.4.7

[Helmut Strey]

Yesterday night, I tried to comile scipy myself with mixed results.
The main problem is that the superpack is compiled using gcc 3.3 and
that the install packages from pythonmac.org are all 4.0.1.
So I used numpy, matplotlib from pythonmac.org and compiled everything
according to the scipy website.  I also installed gfortran from
hpc.sourceforge.org
because I read somewhere that this is the only fortran 77 compiler
that works with
gcc 4.01.

There is only one problem. Not all scipy tests pass.
