Log Message:
* Libtoolize graphics/OpenRM so that we correctly build shared libraries
  on all platforms supported by libtool.

* Remove the unnecessary dependencies on glut and perl, and only use
  perl as a build dependency.

* Use REPLACE_PERL instead of hand-crafted substitution code.

Bump the PKGREVISION for graphics/OpenRM to 2.  Due to the changed
dependency graph, bump the PKGREVISION for packages that use the OpenRM
libraries.  In this case, games/genecys-client is the only one, so
bump its PKGREVISION to 2.
