Ok, I have looked around a bit more and realized, that the py-numpy  
Portfiel uses different compilers for PPC and Intel:

variant darwin powerpc {
         depends_build-append port:gcc41

         post-patch {
                 reinplace "s:MACPORTS_FORTRAN:gfortran-dp-4.1:g" $ 
{worksrcpath}/numpy/distutils/fcompiler/gnu.py
                 reinplace "s:MACPORTS_PREFIX:${prefix}:g"        $ 
{worksrcpath}/numpy/distutils/system_info.py
                 reinplace "s:MACPORTS_GCCPORT:gcc41:g"           $ 
{worksrcpath}/numpy/distutils/system_info.py
         }
}

variant darwin i386 {
         depends_build-append port:gcc41

         post-patch {
                 reinplace "s:MACPORTS_FORTRAN:gfortran-dp-4.2:g" $ 
{worksrcpath}/numpy/distutils/fcompiler/gnu.py
                 reinplace "s:MACPORTS_PREFIX:${prefix}:g"        $ 
{worksrcpath}/numpy/distutils/system_info.py
                 reinplace "s:MACPORTS_GCCPORT:gcc42:g"           $ 
{worksrcpath}/numpy/distutils/system_info.py
         }
}


Started wondering whay that is (why is it?), but also pragmatically  
decided to set i386 to gcc41 as well...
This allowed me to build py-numpy and py-scipy, but using scipy does  
not work, i.e. when trying to "from scipy import *" the symbols,  
python crashes:

Running it in gdb gives the following backtrace:

Why do we need gcc42 for py-numpy?
I'll now try to reinstall gcc42 and py-numpy and see where I get this  
time;/

Greetings,
Jochen
