GRASS is trying to use the C compiler to create the shared library - this 
worked on Linux so I didn't notice it but obviously that must have been 
just luck and it seems not to work on OS X. This clearly is something I 
need to look at and try to fix - none of the other libraries contain C++ 
code so this hasn't come up before.

For now we can probably work around it by creating a static library 
instead of a shared one. Can you try changing the line
default: lib
in lib/iostream/Makefile to
default: stlib
and let me know how you get on?
