OS X is stuck at a known buggy version of g++, namely g++-4.2.1. Conrad has some issues with that upstream, we mostly cope.
I just did a quick grep and symmatl() is defined in a short file fn_symmat.hpp without any #define or #if statement, and that file is directly included. If the code works on other systems, you may be out of luck. Go complain to Apple (about not including a g++ version from this decade) or the FSF (for changing the gcc/g++ license). I don't pick sides here, but I also do not work on OS X. Dirk -- "Outside of a dog, a book is a man's best friend.
