Fix Version/s: None
LSST fftw and numpy 'mkl'-version have namespace collisions, on linux machines. Therefore the LSST build requires a nomkl version of numpy + friends. However, on macs the 'nomkl' option is not necessary and should not be there.
Tim Jenness suggests that lsstsw/bin/deploy should be fixed to avoid using nomkl on macs.
It would be good to fix this throughout our distribution schemes though - conda has a (self-described by Mario Juric) "horrible hack" which should avoid this in future conda releases.
I'm not sure what happens with eups distrib releases, where miniconda is installed first.
But anyway - it would be good to fix this across the board.
