additional requirements (libomp)

Running on OSX, `CyRK` needed an additional package and other minor tweaking for `rydiqule` to load.

I installed `rydiqule` from my local clone with
```
pip install -e .
```

I use `macports` for packages and `bash` as my shell, so the necessary commands were:
```
sudo port install libomp
export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH/opt/local/lib/libomp:
```
