pymol installation

gistfile2.txt

To be able to `import pymol.cmd` in python scripts, it has to be on PYTHONPATH.
If you are building from source (and not buying from schroedinger), i guess it is the "modules" dir that should end up your path in particular. So, follow the vanilla installation (https://pymolwiki.org/index.php/Linux_Install) but the `setup` step ought to be replaced with the follwoing below, where 
`path_to_pymol` is where pymol will be installed

```
python3 setup.py build install --home=path_to_pymol/
--install-lib=path_to_pymol/modules/ --install-scripts=path_to_pymol/
```
After that:
```
export PYMOL_PATH=path_to_pymol/
export PYTHONPATH=$PYTHONPATH:$PYMOL_PATH/modules:
```
