Comment(by howarth@…):

 As posted in reply to complaints about the unfixed breakage from this
 supposed fix to the pymol package[[BR]]
 http://trac.macports.org/ticket/35400[[BR]]

 The tcl maintainers have broken pymol (actually most likely the required
 blt package) by their ill-considered removal of[[BR]]
 --disable-corefoundation. As I have explained numerous times, the Core
 Foundation support in tcl is likely providing some level[[BR]]
 of thread support which is incompatible with tcl programs that use fork()
 without exec(). The sensible fix is already attached to[[BR]]
 this bug report as well as http://trac.macports.org/ticket/31995 where the
 removal of --disable-corefoundation. is moved to[[BR]]
 the threads variant of tcl. Unfortunately the macports tcl maintainers
 seem entirely disinterested in fixing this breakage.
