Issue DM-3463: psfex lapack symbols may collide with built in lapack
On my Mac meas_extensions_psfex fails to build due to the numpy config test failing. "import numpy" fails with: {code} dlopen(/Users/rowen/LSST/lsstsw/anaconda/lib/python2.7/site-packages/numpy/linalg/lapack_lite.so, 2): can't resolve symbol __NSConcreteStackBlock in /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libvMisc.dylib because dependent dylib #1 could not be loaded in /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libvMisc.dylib {code} Our best guess (see discussion in Data Management 2015-08-14 at approx. 1:57 PM Pacific time) is that the special lapack functions in psfex are colliding with the lapack that anaconda uses. In case it helps I see this on OS X 10.9.5. I do not see it on lsst-dev.
