py-numpy build failure, multiple definition of `__i686.get_pc_thunk.bx'

[Charlie Kester]

I've encountered the problem described in PR146801, which unfortunately
was closed without getting to the root cause. (The problem seems to have
gone away as mysteriously as when it appeared. No one seems to know why
either event occurred.)

py-numpy is, as you know, used by many other ports.  
So I'd really like to know how to fix this.

FreeBSD 8.2-PRERELEASE #0: Thu Feb  3 17:45:33 PST 2011

Portstree also updated on Feb 3.

Default python version is 2.7. 
(But pkg_add -r wants to install py26-numpy.  So that solution is unavailable.)
