py25-numpy keeps wanting to install g95 on upgrade

[Daniel Horwood]

When I initially installed py25-numpy I used its +gcc43 variant (which  
removes py25-numpy's g95 dependency), and it installed just fine.  
Today, however, when I tried to upgrade gnome-menus, I had to Ctrl-C  
when I saw that macports had started downloading files for the g95  
port. It took me a while to trace down, but it's definitely something  
to do with py25-numpy.

The receipt in /opt/local/var/macports/receipts/py25-numpy/ 
1.0.4_7+gcc43/  correctly lists the variant as +gcc43, so I'm not sure  
what's going wrong.

Here are the bottom few lines of output from '$ sudo port -dv upgrade  
py25-numpy':

Steps to reproduce:
1. sudo port install py25-numpy +gcc43
2. sudo port upgrade py25-numpy

My system: macports 1.6; OSX 10.5.2 (Intel)

I'll file a bug once I confirm this isn't user error, but I have a  
feeling that it's the funky way that the py25-numpy sets +g95 as a  
default variant within a conditional block.
