Comment (by kencu):

 Replying to [comment:5 giovannicantele]:

 > That means that libgcc-devel puts libgfortran.5.dylib in a non-standard
 path (under libgcc under lib), that causes the issue. This is probably a
 bug or an issue, in any case.

 MacPorts installs gcc's libs in a supported {{{libdir}}} which is
 {{{/opt/local/lib/libgccN}}}. Those are then symlinks to the actual
 libraries installed in {{{/opt/local/lib/libgcc}}}.

 This is a perfectly reasonable installation plan that was done for a good
 reason, and has been like this for 15 years or so.

 Recent changes to gcc-devel for arm did not properly support having gcc
 libraries in their own set {{{libdir}}}, in particular manifest when using
 @rpaths.

 That is an upstream gcc bug that was hopefully fixed by the PR.

 But now that fix needs to propagate down the chain, be verified to fix the
 problem, and then everything that was ever built with gcc-devel needs to
 be rebuilt so it will pick up the new rpath references (to gcc's own
 libdir).
