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:

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.

to set macports to install i386 I uncommented that line in macports.conf

I cannot reproduce your issue.

I'm on Lion with python port installed with universal variant and py27-numpy built for i386 architecture. Check following output:

~ $ port -v installed python27
The following ports are currently installed:
  python27 @2.7.2_4+universal (active) platform='darwin 11' archs='i386 x86_64'
~ $ port -v installed py27-numpy
The following ports are currently installed:
  py27-numpy @1.6.1_1 (active) platform='darwin 11' archs='i386'
~ $ port select --show python
The currently selected version for 'python' is 'python27'.
~ $ which python
/opt/local/bin/python
~ $ python

Should be fixed in r91289, I've tested it in both i386 only and +universal variant, provides shared objects with coherent architecture.

That's a workaround; the real fix is of course to stop it from building in the destroot phase at all.
