Completely unrelated but now that you mentioned gfortran: I installed it from 
Homebrew (http://brew.sh) and I've been using it ever since without problems -- 
I even compiled SciPy with it on my Mac.

Hmmmm... this is almost the very last linking step so you are almost there. But 
the fact that the compiler looks for libiconv.la is weird to say the least.

igraph surely depends on libiconv, but only indirectly. igraph requires libxml2 
to be able to parse XML files (in order to load graphs stored in GraphML 
format), and it is libxml2 itself that requires libiconv. When igraph is linked 
dynamically (into a .dylib), it does *not* require libiconv because the OS 
linker will resolve the libiconv dependency when libigraph loads libxml2. Are 
you trying to compile igraph statically by any chance?

Also, since libxml2 is required only for reading GraphML files, can you try 
recompiling the C core with "./configure --disable-graphml" just to see where 
that leads?
