Github on wormwood

OK, two things to know.

Need to set up ssh for multiple keys. See e.g.
http://www.karan.org/blog/index.php/2009/08/25/multiple-ssh-private-keys
Need to do this:
```
$ ssh-add ~/.ssh/id_rsa_github
```

On gelato, I need something like this:

$ exec ssh_agent bash<br />$ ssh-add ~/.ssh/id_rsa_github

Bye.

Using slicer on SPL computers

When you try to run slicer remotely on the SPL computer, you get something like this:

$ ./Slicer-build/Slicer
Number of registered modules: 94
ERROR: In /home/gcs6/build/slicer-rt/SlicerRt-build/VTK/Rendering/vtkXOpenGLRenderWindow.cxx, line 404

It seems you can workaround by doing this:

$ setenv LIBGL_ALWAYS_INDIRECT y
