Milestone: MacPorts 2.7.0
Port: gcc6 added
Summary: problem fortran → gcc6 @6.4.0: dyld: Library not loaded: /opt/local/lib/libisl.15.dylib

The error message shows that you have gcc6 @6.4.0, which is years out of date. (We updated gcc6 to 6.5.0 in 2018.) And it failed to work because it is linked to an outdated version of isl which is no longer present.

The fix is to upgrade to gcc6 @6.5.0. I'm not sure why running sudo port upgrade outdated didn't do that for you.

What do you see when you run port installed gcc6?

Why did you have to sudo port -f activate libgcc10? You should not need to force activate anything.
