Yes (g77-3.4 g++ 4.1.2 lib2c0-dev) from the configure file provided by developers. No errors in either the serial or parallel compilations (openmpi). Also, there is a very long test for both the serial and parallel execution. All passed with a few marginal warnings for different precision on different machines. Finally, docking of a slightly smaller ligands occurs with no errors.
