 I'm working on Ubuntu 10.10/11.04, and Opensuse 11.4. I installed Gentoo
 prefix on both systems and compiled the blas lapack and atlas versions
 from.

 No I installed numpy linked with the libraries from prefix
 On Ubuntu it worked fine. On openSuse I got the following error message
 when I try to import numpy

 {{{

     from numpy.linalg import lapack_lite
 ImportError: liblapack.so.0: cannot open shared object file: No such file
 or directory
 >>> quit()
 }}}

 but blas, lapack and atlas should have been built properly.

 Then after some other failed experiments I tried my build of
 lapack_lite.so from ubuntu in the opensuse version and got this:


 {{{
 ....
     from numpy.linalg import lapack_lite
 ImportError: liblapack.so.3gf: cannot open shared object file: No such
 file or directory
 }}}

 when I opended with emacs the lapack_lite.so with my emacs I found this
 entry within the assembler code:


 {{{
 liblapack.so.3gf...libblas.so.3gf
 }}}

 The gag behind this is that this doesn't appear in my directory where I
 installed blas, lapack and atlas but in my /usr/lib directory. But my site
 cfg holds the following:


 {{{
 [atlas]
 include_dirs = /home/maldun/Gentoo/usr/include
 library_dirs = /home/maldun/Gentoo/usr/lib/blas/threaded-
 atlas:/home/maldun/Gentoo/usr/lib/blas/reference:/home/maldun/Gentoo/usr/lib/lapack/atlas:/home/maldun/Gentoo/usr/lib
 atlas_libs = cblas, atlas, blas
 lapack_libs = lapack, blas, cblas, atlas
 [blas_opt]
 include_dirs = /home/maldun/Gentoo/usr/include
 library_dirs = /home/maldun/Gentoo/usr/lib/blas/threaded-
 atlas:/home/maldun/Gentoo/usr/lib/blas/reference:/home/maldun/Gentoo/usr/lib
 libraries = cblas, atlas, blas
 [lapack_opt]
 library_dirs =
 /home/maldun/Gentoo/usr/lib/lapack/atlas:/home/maldun/Gentoo/usr/lib/blas/reference:/home/maldun/Gentoo/usr/lib/blas
 /threaded-atlas:/home/maldun/Gentoo/usr/lib
 libraries = lapack, blas, cblas, atlas
 }}}

 and those files are not located there!

 My PATH, LIBRARY_PATH, and LD_LIBRARY_PATH also don't point there:


 {{{
 maldun@math112:~/Gentoo$ echo $LD_LIBRARY_PATH
 /home/maldun/Gentoo/usr/lib:/home/maldun/Gentoo/lib/
 maldun@math112:~/Gentoo$ echo $LIBRARY_PATH
 /home/maldun/Gentoo/usr/lib:/home/maldun/Gentoo/lib/
 maldun@math112:~/Gentoo$ echo $PATH
 /home/maldun/Gentoo/usr/bin:/home/maldun/Gentoo/bin:/home/maldun/Gentoo/opt/bin:/home/maldun/Gentoo/usr/sbin:/home/maldun/Gentoo/sbin:/home/maldun/Gentoo/usr/x86_64
 -pc-linux-gnu/binutils-bin/2.21.51.0.7:/home/maldun/Gentoo/usr/x86_64-pc-
 linux-gnu/gcc-bin/4.4.5
 }}}

 This shouldn't be happening if I want to build exclusively with one
 version of BLAS/LAPACK/ATLAS, but I don't know how to fix this issue!

 Please help me!

 greez,
 maldun
