Nu language update SnowLeopard

[Andrea D'Amore]

Hello,
version 2.0.1 of Nu, latest stable from website, doesn't build on
Lion. Github repository from Nu's author has a "lion" branch but
that's failing for me as well, it's using clang as default and I get a
lot of syntax error for objC files.

I've updated the portfile in order to fetch tarball from a fork of Nu
[1] that builds on Lion, I'd like a confirm that patch at [2] builds
on SnowLeopard as well.


Regards
