Before I get into my email, I noted earlier that you were using gentoo.
Why not just 'emerge -v numeric'? It should take care of dependencies
automatically. You might need to do some tweaking to your USE flags to
enable optional dependencies that you want.

This must always be done when installing a new library. A lot of the
time it is transparent since 'make install' will run it for you, and
distributions usually run it in startup scripts.

/usr/lib must be listed in /etc/ld.so.conf for ldconfig to pick up on
it. I can't imagine its not listed there, though...
>Slightly off topic, LD_LIBRARY_PATH did not exist, should I add it to
It is normal for this environment variable not to exist. I believe
LD_LIBRARY_PATH is only for finding libraries at runtime, so would not
affect a compile... don't quote me on that though.
My only guess is that the libraries in question are not readable by the
user running setup.py. Try an 'ldd /usr/lib/liblapack.a' (and the rest
of the libraries), I believe it will give an error message if you don't
have the permissions it needs, which happen to correspond to the
permissions needed for compiling software with it.
