This can happen on Mac OS X due to a system upgrade, such as an upgrade to Mountain Lion. The fix is simply to reinstall Gurobi Optimizer. And you might as well upgrade to the latest version while you do that. Remember that a new license key is not required unless your license key has either expired or it was for a different major version -- for example, if you had a license for version 4 after version 5 was released.

This isn't an issue of knowing the Python shell.
Also, you don't have to use the Python shell. You can use gurobi_cl, MATLAB, R or any of the traditional APIs -- C, C++, Java or .NET.

Thanks Greg. It works now and, not surprisingly, is much faster than glpk.
