Comment (by jhowarth@…):

 For some reason port has regressed such that when it begins to execute the
 post-destroot the following symlink has already been errorenously
 created...

 % ls -l
 "/opt/local/var/macports/build/_Users_howarth_ports_science_pymol/pymol/work/destroot/opt/local/bin/pymol"
 lrwxr-xr-x  1 root  admin  69 Oct 31 16:02
 /opt/local/var/macports/build/_Users_howarth_ports_science_pymol/pymol/work/destroot/opt/local/bin/pymol
 -> /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/pymol

 So apply the ugly hack below will purge it until we discover why port is
 misbehaving.

 Of course, the most annoying bug of all in pymol is how utterly useless
 the "require_active_variants" field is.
 From a  clean install of MacPorts on Yosemite, with the first install
 being "sudo port -d install pymol", port
 totally ignores the lines...

 require_active_variants tcl "" corefoundation

 require_active_variants tk "" quartz

 which should be preselecting the appropriate tcl and tk variants. You have
 to manually execute...

 sudo port -d install tcl -corefoundation

 sudo port -d install tk -quartz


 to unbreak the installed pymol.
