Linalg on OS x

Hi all,
I am trying to use the linalg library
(http://rubyforge.org/projects/linalg/) on my OSx machine. The install
file for linalg says that it is dependent on LAPACK. Does anyone have
any experience setting up linalg on OSx? I was wondering if I could use
the vecLib framework that ships with OS x or if I need to install LAPACK
via ATLAS or some other way. If I can use vecLib how would I go about
doing that? If any one has installed linalg on OSx before any pointers
would be helpful. Thanks!
