Hi Jarno

I will test your patch from your previous mail and report to this list. Since 
MacPorts' ATLAS has gcc44 as a library dependency and I have atlas 
@3.8.3_4+gcc44 active, I assume it's better to try gcc44 (instead of gcc45) 
first.

Do you have any suggestions how I have to build ATLAS (e.g. from MacPorts) such 
that I can use it instead of the Apple version for my package? test_control.m 
[1] succeeds when my oct-files use vecLib, but they fail [2] with MacPorts' 
current ATLAS settings.
