Hello,

I am very new to firedrake and trying to install it on two machines: ubuntu and mac.  I am having problems with each and thought I would start asking about the ubuntu.

running firedrake-install seemed to work.  At least I didn’t notice any errors.

However, when I do an upgrade, I get that there is a problem with PETSC_DIR not being defined.  Is this something that we should specify ourselves?

Thank you in advance.

Francis
