Thank you for your helpful reply.

These are the two lines I added to my `.bashrc` that resolve the error
I was getting:

```
unset GHC_PACKAGE_PATH
export LD_LIBRARY_PATH=/run/current-system/profile/lib/
```
Note: The LD_LIBRARY_PATH variables was empty. If it was not I would
have appended to the existing LD_LIBRARY_PATH variable.
