Title: Mac Lion Support

I was getting the following error when trying to do a "gem install"
```
g++ -DHAVE_CONFIG_H -I. -I/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin11.0 -arch i386 -arch x86_64 -g -Os -pipe -fno-common -DENABLE_DTRACE -fno-common -pipe -fno-common -fno-common -I/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/universal-darwin11.0 -MT Class.o -MD -MP -MF .deps/Class.Tpo -c -o Class.o Class.cpp
llvm-g++-4.2: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags
```

I added Darwin 11.0 to extconf.rb, treating it the exact same as Darwin 10.0. Works on mine, could not find any test cases to add / modify.
