New Revision: 352516
URL: http://svnweb.freebsd.org/changeset/ports/352516
QAT: https://qat.redports.org/buildarchive/r352516/

Log:
  Convert celestia ports to stage
  
  While here add a couple of patches obtain from the fedora project to fix
  compilation with modern compilers and allows to build with lua 5.2
  Switch lua to lua 5.2 version
  Use desktop file provided by upstream instead of the version provided in
  the ports (the upstream version is more complete)
  Switch to USES=libtool
  Now that overlinking is not happening anymore fix the glut version not
  linking properly because it lacks an explicit link to libGL.
