Brian:

I didn't follow that suggestion.  And, since --disable-shared did the trick, I 
didn't explore the problem further (you may also need to set LDFLAGS to '-Si' 
when you are linking to your code).  But, I did bring up the multiple 
definitions issue with Apple.  They told me that there are a few remaining 
issues with OS X that they are trying to resolve related to Mach-O libraries and 
this may be a side-effect.

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.

So changing the link order, as mentioned the other day, wouldn't help?

Thanks
