Hello,

I started trying to install firedrake on a cluster and I have some rather silly problems.

First, it won't install because PYTHONPATH is installed.  That's easy to resolve since I can ask it to honour the python path and then it goes forward.

Second, it notices that there is a PETSc directory.  I am pretty sure that I won't the install script to build petsc and not use what's there. 

IS there a way to get it to ignore both of these?  I tried

PYTHONPATH=''

but that didn't seem to help for the first part so I don't imagine it will help much for the second.

The good news is that the default python is 2.7.8

Any advice would be greatly appreciated to get by the python and petsc path's already set?

Cheers, Francis
