Can you start by telling us which Fortran compiler you have installed 
(the manual mentions several), and where 
/usr/local/lib/libquadmath.0.dylib came from?  AFAIK all the recommended 
compilers install it in /usr/local/gfortran/lib.

I'd try moving /usr/local/lib/libquadmath.0.dylib aside (and any other 
libs that look like those in /usr/local/gfortran/lib).
