>Description:
eigen2 uses aligned malloc routine (ei_aligned_malloc), which currently relies on posix_memalign. The latter is not available on 6.x, so dependent ports may fail to build (example is upcoming science/avogadro, ports/134710).

FreeBSD malloc, however, is guaranteed to return 16-byte aligned pointers, so it may safely br used instead of posix_memalign, on 6.x as well.

The patch mekes EIGEN_MALLOC_ALREADY_ALIGNED defined on FreeBSD, so malloc is used.
