 doxygen currently needs coreutils for ginstall which is being checked for
 by configure.
 However, it does not really require coreutils's ginstall, the BSD variant
 is sufficient.

 Personally spoken, I find installation of coreutils is evil, and for
 doxygen it only bloats the installation process.

 Portfile patch attached.
