Description
After sudo install atlas guile16 hdf5-18 libpng fftw-3 But the atlas build has been stuck for more than 2 hours. Is it normal?
I am using a 2.6GHz quad-core, 16GB Mac Mini with Maverick and MacPorts 2.2.1. gcc installed is 4.9.

atlas does take several hours to build, even on fast hardware.

Atlas does a lot of runtime optimizations by trying out oodles of possible combinations of different parameters tied to inner hardware (e.g: cache size, cache line size, vector unit size, prefetch policy, and so on). Since it takes measures, it cannot compile multithreaded because each thread would more or less interfere with its neighbor. Therefore, it has its own internal handling of threading during compilation. Just be patient, it should be rewarding at the end.
This is probably #38766
