Hey Mike - thanks for giving me a hand.

So I installed the libffi-devel package and then got past the initial
error that I had and on to a new one. I have managed to install
version 0.6.2, but I am getting the following errors for 0.6.3...
(sorry about the massive copy-paste)

I don't think this is an environment issue. NATIVE_MAPPED is defined in Types.h, which is included by Type.h, which is included by MappedType.c on line 33. So I'm at a loss to explain what's going on.

Perhaps if you included some information about your platform - what distro, version of GCC, etc., someone might have deeper insight than I do.

Good luck,
