I will, thanks! I may need some more help, I  hope that’s OK.
If I may I’ll give a brief overview of what I want to do:

I used to serve on the ISO C++ committee but got a bit tired of it
so I implemented by own language (Felix). It generates C++ code
which is then compiled by the system compiler (gcc or clang and hopefully
later MSVC++).

I have an interest in performance, science, multi-threading etc etc.
I have recently implemented a parallel for loop and compared the
performance of a simple serial algorithm multiplying a matrix A by
a matrix B (transposed) with a couple of other methods. I’m running
on a nice new Macbook Pro with 16G Ram and 2.2G Intel i7.
Running OSX 10.10 (Yosemite). The native compiler is clang 3.3,
and “gcc” is linked to it (so a script saying “gcc x.c” is actually 
running clang not gcc).

I am currently building a GSL binding, which includes the CBLAS interface.
I have a copy of GSL and its CBLAS, and gotoBLAS so its time for Atlas..
I’ve been a lurker here for some time, but now I have a box fast enough
to do something :-)

To build Atlas it seems I need Fortran among other things.
I am going to try to use

	http://hpc.sourceforge.net/

which has gcc 5.1 and gfortran for OSX as a binary. I tried this some time
ago but it wouldn’t link correctly (and seemed confused about libraries).
Author seems to be:

Gaurav Khanna 
Physics Department 
University of Massachusetts at Dartmouth 
North Dartmouth, MA 02747.

Hope it works :)

I have no idea how to configure or tune Atlas but I guess we’ll get to that :)
