Python-numpy broken

Question

Ok, my first pacman upgrade error ever I haven't been able to solve by a search in this forum, I'm afraid it might not be so straight forward.
Last night doing a pacman -Syu gave me an error that said gcc-fortran was missing, found this http://bbs.archlinux.org/viewtopic.php?id=45642 thread and made a change in the PKGBUILD dependecy list from "gcc-fortran" to "gcc-libs". After that pacman -Su worked.
However, today trying to work on a school project requiring python-numpy I got this error while trying to run my code:
File "/usr/lib/python2.5/site-packages/numpy/linalg/linalg.py", line 25, in <module>
from numpy.linalg import lapack_lite
ImportError: libgfortran.so.2: cannot open shared object file: No such file or directory
A quick look in /usr/lib/ showed no libgfortran.so.2 file but a libgfortran.so.3 file. Hoping for a quick fix so I could continue my work I made a symlink libgfortran.so.2 -> libgfortran.so.3. But it gave me this error:
File "/usr/lib/python2.5/site-packages/numpy/linalg/linalg.py", line 25, in <module>
from numpy.linalg import lapack_lite
ImportError: /usr/lib/libblas.so.3: undefined symbol: scabs1_
I would guess that the python-numpy package isn't updated to use the new fortran libs? If anyone have any idea how to fix this I would be greatful.

Answer 1

Ok, I finally had time to fix this, and learned a bit about Arch/ABS too
For inexperienced users with the same problem as me this is what i did:
1. Installed ABS and ran 'abs' as root (more info here http://wiki.archlinux.org/index.php/ABS … ild_System )
2. Copied the files in /var/abs/extra/science/blas/ to a folder in my ~
3. nano Makefile -> add 'scabs1.o' to the end of the OBJS list, save & quit. (info from here: http://bugs.archlinux.org/task/9905?pro … &pagenum=2 )
4. md5sum Makefile -> replace old md5 in PKGBUILD, save & quit.
5. as user, 'makepkg'
6. as root, pacman -U blas-19980702-4-i686.pkg.tar.gz
Now it seems to work, thanks for the help!
