--------------------------------------+-------------------------------------
 The change in pymol 1.5 to no longer support 'python setup.py build' but
 only use [[BR]]
 'python setup.py install' to both build and install pymol has broken the
 previous[[BR]]
  infrastructure in the Portfile for building compiler variants of the
 package. The [[BR]]
 attached Portfile.diff...[[BR]]
 [[BR]]
 1) Updates the package to current pymol svn[[BR]]
 2) Adds the gcc47 compiler variant[[BR]]
 3) Changes the build.env to destroot.env to that the compilers are set
 from[[BR]]
 configure.compiler [[BR]]


 Tested on Lion for standard and +gcc45 variant builds.
