libX11 not found

I come from interpreted languages and now I’m starting with C, so I’d like to test CINT.
I’m on macosx 10.8 and I followed this: … tain-lion/

Now, I get this while launching ./configure:

libX11.lib libX11
library not found
Result: configure: libX11 MUST be installed

sorry for the dumbness, any suggestion highly appreciated!
