Building LÖVE 9c7510832f8b633de1cf58368cffa6bb7bb9b958 on OS X 10.9 with
make is failing:

The log has much more of the same; I'll attach the whole thing. But it might all come down to the unknown
_GLIBCXX_BEGIN_NAMESPACE type name.
On OS X these days, the compiler used is the Apple LLVM compiler, which is based on the open source clang compiler. There is no GCC.
$ clang -v Apple LLVM version 5.0 (clang-500.2.79) (based on LLVM 3.3svn) Target: x86_64-apple-darwin13.0.0 Thread model: posix
In addition, OS X 10.9 removed
libstdc++ which was used on OS X 10.8 and earlier and replaced it with
libc++ which behaves somewhat differently sometimes. If I understand correctly, it implements the C++11 standard, but not some of the not-quite-standard ways that were in use before the standard was finalized.
I'm not a C/C++ programmer so my ability to fix this problem in the LÖVE source code is limited, but I'm happy to test any changes you propose.
