py-numpy and 32bit systems

[Riccardo Mottola]

Hi,

I have a situation where I am unable to upgrade cleanly on my MacBook, 
took me a bit to realize.
In the past, I had a complete systems, maybe also helped to have Ken's 
ports overlay.

While doing upgrade, I am stuck on several rebuild failures (not 
installing anything new). One is:

https://trac.macports.org/ticket/69199

which is I understand related of this: 
https://trac.macports.org/ticket/66685

py-numpy doesn't build in its openblas variant on 32bit intel.
Of course, best would be to fix it :)

Second would be: how can I get the dependency chain? that is, why do I 
need it? I tried rdepof / rdependentof / rdepends and always get itself. 
I don't like nor use python, so any installed port of it is always a 
dependency :)

Understanding what it needs would answer if it needs the openblas 
variant or not.
