Atlas build hangs - El Capitan

[paultbaker@…]

I'm trying to build Atlas on OSX 10.11.4 (MacBook, Pro early 2015). The build hangs. I know Atlas takes a very long time to compile. I left it running for about 24 hours.

Running sudo port -v install atlas, the build stopped at:

make[2]: Leaving directory `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_atlas/atlas/work/ATLAS/build/bin'

At this point no processes with user 'macports' were active. xatlas_build was still alive, but not doing anything. I ctrl-C killed the build.

Rerunning the same command (without cleaning) to try to resume fails outright:

Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_math_atlas/atlas/work/ATLAS/build" && /usr/bin/make -w build 
Exit code: 2
Error: org.macports.build for port atlas returned: command execution failed
Warning: targets not executed for atlas: org.macports.activate org.macports.build org.macports.destroot org.macports.install
Please see the log file for port atlas for details:

I forgot to mention -- Xcode 7.3.1, fortran compiler via gcc5 installed with MacPorts.

Currently rerunning after a clean.

In the future, please Cc the port maintainers (port info --maintainers atlas), if any.

After clean and rerunning install, it started chugging along again. It ran to completion. Don't know what the initial hang-up was, but It eventually built...
