 this intentionally. When I get to the machine, I will check the content of
 `/Library/Python/2.7/site-packages/`. But to my understanding, as long as
 I use MacPort, this content should be ignored, but apparently it is no.

 I can understand your confusion. MacPorts can't (yet?) sandbox itself from
 having its subprocesses access things outside /opt/local (or where ever
 MacPorts is installed). So, lots of configure and python scripts try to
 find everything it can on the system. In this case, someone on the machine
 installed a package outside of MacPorts that contains numpy. This package
 is interfering with the build of scipy. Basically, it is equivalent to
 installing something into /usr/local,
