David, thank you for this explanation. Installing py33-scipy +gfortran worked. However, I have these notes.

No, I can't see this because I'm not schooled in the arcania of MacPorts. I'm just a semi-sophisticated user following the admonishment to update his MacPorts installation.

I never selected any variants; any installation of py33-scipy was handled by the ports system.

Why is this not handled automatically? If I can type sudo port install py33-scipy +gfortran and the upgrade script recognizes the problem then why can't the upgrade script handle it?

I humbly submit that this is poor design, and wonder why it is not a bug.

Please understand that these comments are not directed at you but at the community at large.
