The macport distribution seems buggy. You should report to them.

The CGAL project does not support the Apple "clang" before MacOS X 11.4. On
10.7, you need to use a real GNU gcc (not the one packaged by Apple). Maybe
you can use macport to install a regular gcc version.

Changing to gcc compiler solves the problem.
