py-numpy: oportunistic linking agaist openblas results in build failure

[epaell]

While attempting to upgrade py27-ipython macports failed to upgrade py27-numpy (running on Yosemite). The previous version of python/numpy worked fine. The upgrade also fails for py34-ipython with the same apparent mode of failure.

Build log for py27-numpy

Is this still actual since @1.9.2 is out?

Looks like surreptitious linking with OpenBLAS; probably need to tell NumPy to disable OpenBLAS support, so that it won't be used even when it is installed already. If you don't need OpenBLAS, can you deactivate it, clean py27-numpy, and then try the install again:

sudo port clean py27-numpy
sudo port -f deactivate openblas
sudo port install py27-numpy

you can even "activate" openblas again now if you want to. I'll look into disabling the surreptitious linking.

After installing OpenBLAS, I see this error too; so it really is surreptitious linking with OpenBLAS.

I recall, I have already observed this opportunistic linking against OpenBLAS before. Apparently, that was for py-scipy, but it might be related as py-scipy relies on py-numpy and its build system. There the ticket for reference: #46763.

Hopefully fixed in r139293.
