Comment (by mojca@…):

 I fetched your patches and did some slight modifications:
  * used a `python` `PortGroup` instead of the outdated/deprecated
 `python26`
  * switched to `python27`, removed dependency on `python` (it should
 already be added by the `PortGroup`)
  * also added the `gcc49` variant
  * the latest version in SVN doesn't use dependencies on `gcc4x` ports, so
 I also removed that from `gcc48`, even though I didn't test those options
  * fixed a few offsets and "fuzzes" in the patches
  * replaced tabs with spaces in some patches (I'm not sure how python
 handles mixtures of tabs and spaces, so just in case)
  * adjusted some whitespace in the `Portfile`

 I noticed that the version in SVN is now 4039, but I didn't dare to change
 that.

 I didn't do any extensive testing of the port. If you agree with these
 changes, I'll commit them.

 If you need to upload a large number of files next time, please do a
 unified diff like the one I attached:
 {{{
 svn co
 https://svn.macports.org/repository/macports/trunk/dports/science/pymol
 cd pymol
 # do your modifications
 svn diff > output-file.patch
 }}}
