py27-numpy ignoring build_arch because of building in destroot where ARCHFLAGS isn't set

[joanmanel@…]

I set in macports.conf to use i386. I am using right now Lion 10.7.3, and this is a Macbook 5,2. If I don't set it to i386 it installs everything 64, but I need to install everything in 32 because I need opencv in 32.

The installation is Ok, but then when in python loading numpy:

python2.7 Python 2.7.2 (default, Mar 27 2012, 16:48:41) [GCC 4.2.1 Compatible Apple Clang 3.1 (tags/Apple/clang-318.0.58)] on darwin Type "help", "copyright", "credits" or "license" for more information.

I installed this 3 days ago, in SL and macports for SL, and it worked perfectly. Then I updated my SO to lion, cleaned everything about macports, installed macports for Lion and as you can see it isn't working.
