GSL-0.9 on Mac OS X

[rodney sparapani]

Mac OS X can probably be added to the officially supported list.  Due to 
some problems with dynamic linking, you need to:  ./configure 
--disable-shared
But, this is an issue with OS X, in general, and not peculiar to GSL.  
There 2 failures with "make check", but it appears to be the tolerances; 
see below.
