[SciPy-dev] [mlabwrap] linker path

If I understand correctly, mlabwrap is now maintained as part of the scikits
project. Since the latest release 1.1-pre from the old project site does not
even compile out of the box, I'm assuming the latest version from the SVN
repo is the most usable one.

However, contrary to 1.1-pre (after fixing it up with the patch below), it
requires matlab to be added to the linker path. I really don't want that,
because matlab contains old versions of standard libraries such as zlib and
libstdc++. Since we only need libeng.so, libmat.so, libmx.so and libut.so,
wouldn't it be much nicer to create a directory with symlinks to those
