#38516: update pymol to newer svn and add fixes
-----------------------+--------------------------------
 Reporter:  howarth@…  |      Owner:  macports-tickets@…
     Type:  update     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.1.3
 Keywords:  science    |       Port:  pymol
-----------------------+--------------------------------
 The attached Portfile.diff and revised setup_py.diff patch updates pymol
 to the current svn revision 4024.[[BR]]
 It also adds support for the gcc48 variant and adopts the same approach as
 Fedora towards eliminating the use[[BR]]
 of the pymol_path symlink. The patch to setup.py is also adjusted to
 handle the changes in current svn regarding[[BR]]
 the prefix_path search by placing macports' directory first. Note that the
 breakage in the apsb tools plugin from the[[BR]]
 switch to tcl/tk 8.6 still exists and I am awaiting for a fix from the
 developer (if one exists for the current blt code).
