I’m not familiar with ATLAS but I think you need to choose one of the variants
in order to build it with another compiler:
$ port variants atlas
atlas has the variants:
gcc49: build using macports-gcc-4.9
* conflicts with gcc5 mpclang37 perf
gcc5: build using macports-gcc-5
* conflicts with gcc49 mpclang37 perf
mpclang37: use mp-clang-3.7 and gfortran
* conflicts with gcc49 gcc5 perf
nofortran: Forgo use of fortran compiler
universal: Build for multiple architectures
Perhaps try
sudo port install atlas +gcc5
Also, some packages can take a very long time to build. Adding the verbose
flag can give you more feedback as the build progresses:
sudo port -v install atlas +gcc5
