In fact you just need to change the path, as that library is included in 
the CRAN R distribution (which I guess is what it being used, although 
no one said which R it was).  Look in 
/Library/Frameworks/R.framework/Versions/Current/Resources/lib  ....

It is also most likely possible to link against a static libgfortran, as 
we do on Windows.

But this is indeed the wrong list: see the posting guide which it seems 
neither of you have read.  Follow-ups to R-sig-mac ....
