Pymol @1.7.1.1on Yosemite

[sean.connell@…]

Hello I am have problems running pymol @1.7.1.1 under Mac OS X 10.10. I was first using a version that worked under OS X 10.9 but after the upgrade it failed with this error:

 Detected OpenGL version 2.0 or greater. Shaders available.
 Detected GLSL version 1.20.
 OpenGL graphics engine:
  GL_VENDOR:   NVIDIA Corporation
  GL_RENDERER: NVIDIA GeForce GT 750M OpenGL Engine
  GL_VERSION:  2.1 NVIDIA-10.0.43 310.41.05f01
Mac OS X 10.10000 or later required !
Abort trap: 6

Then following the instructions on mac port I tried to remove and reinstall pymol with:

sudo port uninstall pymol
sudo port install pymol

and now the installation files with:

Error: org.macports.destroot for port pymol returned: error copying "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_science_pymol/pymol/work/pymol/setup/pymol_macports" to "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_science_pymol/pymol/work/destroot/opt/local/bin/pymol": file already exists

Hi. I think I know the cause of the abort trap problem.

Two seconds of searching seems to indicate that PyMOL uses Tkinter. A bug has recently been filed in Tk for Yosemite - ​http://core.tcl.tk/tk/info/1d37c3e16616a0e6283ef390272f0cf483b74b5f - which produces the same error.

While I feel the pain of this problem, I'm not sure how it can be solved. If it's a problem in Tk itself, then it may be outside the scope of MacPorts. Hoping that someone else can provide a suggestion or hope of a solution.

Turns out that the Tk bug was filed in relation to MacPorts ticket #45444

The reason why you get an error copying is presumably that you did not ​run "sudo port clean pymol" before trying to install it.
