"cannot run C compiled programs" when running rvm install

If you get this error in your config.log when running rvm install <version>, you may have the wrong rvm_archflags set in your ~/.rvmrc.

Mine was set to:

rvm_archflags="-arch x86_64"

When it should have been:

rvm_archflags="-arch i386"

I don't know how that happened, but there you go. Hopefully this has solved it for you.

Mine was not compiling because SDKROOT was pointing to iPhone simulator. I unset the env var and it worked.
