numpy would not load: libgcc_s vs. libgfortran

[Mikhail T.]

Hi!

I built py-numpy only a few weeks ago with default config options (I
think). I'm trying to port some numpy-using software now and its
self-tests fail with the following error:

    ...
        import numpy
      File "/opt/lib/python2.7/site-packages/numpy/__init__.py", line
    180, in <module>
        from . import add_newdocs
      File "/opt/lib/python2.7/site-packages/numpy/add_newdocs.py", line
    13, in <module>
        from numpy.lib import add_newdoc
      File "/opt/lib/python2.7/site-packages/numpy/lib/__init__.py",
    line 8, in <module>
        from .type_check import *
      File "/opt/lib/python2.7/site-packages/numpy/lib/type_check.py",
    line 11, in <module>
        import numpy.core.numeric as _nx
      File "/opt/lib/python2.7/site-packages/numpy/core/__init__.py",
    line 14, in <module>
        from . import multiarray
    *ImportError: /lib/libgcc_s.so.1: version GCC_4.6.0 required by
    /opt/lib/gcc48/libgfortran.so.3 not found*

I checked all of the shared objects installed by numpy with ldd. All
report properly using the /opt/lib/gcc48/libgcc_s.so.1 (installed by the
gcc48 port) rather than the stock /lib/libgcc_s.so.1. For example:

    /opt/lib/python2.7/site-packages/numpy/core/multiarray.so:
            libblas.so.2 => /opt/lib/libblas.so.2 (0x801780000)
            libm.so.5 => /lib/libm.so.5 (0x8019d2000)
            libpython2.7.so.1 => /opt/lib/libpython2.7.so.1 (0x801bfb000)
            libc.so.7 => /lib/libc.so.7 (0x800820000)
            libgfortran.so.3 => /opt/lib/gcc48/libgfortran.so.3
    (0x801fbc000)
    *        libgcc_s.so.1 => /opt/lib/gcc48/libgcc_s.so.1 (0x8022d2000)*
            libquadmath.so.0 => /opt/lib/gcc48/libquadmath.so.0
    (0x8024e8000)
            libthr.so.3 => /lib/libthr.so.3 (0x802723000)
            libintl.so.8 => /opt/lib/libintl.so.8 (0x802948000)
            libutil.so.9 => /lib/libutil.so.9 (0x802b53000)

And yet, the error occurs...

Has anyone else seen this? Thanks! Yours,
