Hi,
Were these commands working on a lower-number version of your Mac OS? Or is this the first time you are running them on the Mac? In the latter case, I wonder if you don't have GSL (the GNU Science Library) downloaded, which can be gotten via fink:
`sudo fink install gsl'. Otherwise, they are available via the GNU website: [
www.gnu.org] .
Please let me know if that solves the issue or not.
Cheers,
pt
