trying to install ATLAS

pagani laurent via macports-users
Hello,

Running Mac OS 10.12.6, I try to install ATLAS with macports but 1) it selects /usr/bin/clang as a C compiler (why not the /opt/local/bin/gcc one ?), 2) it selects gfortran7 which does not exist and 3) it hangs up on the building. After more than one hour, still there :

still there after > 1hour
The package mentions that it depends on gcc5 but I have gcc7 only (cleaned the previous versions). Can this be a problem ?
I found no ticket mentioning similar problem (but Veence requiring a gcc6 version)

Thanks for any help,
Laurent
