delocate.delocating.DelocationError: .dylibs/libgfortran.5.dylib already exists

This worked in the past but suddenly I get an error when running delocate-path on a folder where multiple executables rely on the same dependency (I’m assuming that’s what the error is about): “delocate.delocating.DelocationError: .dylibs/libgfortran.5.dylib already exists”. Am I doing something wrong?

OK, I found the issue.

libgfortran.5.dylib was a direct dependency of the executables listed above, but also an indirect dependency via libnetcdff.6.1.1.dylib (which is not listed in delocate-listdeps). The catch was that the direct dependency came from /usr/local/Cellar/gcc@8/8.3.0/lib/gcc/8/libgfortran.5.dylib and the indirect one from /usr/local/Cellar/gcc@9/9.1.0/lib/gcc/9/libgfortran.5.dylib. delocate then couldn’t handle the situation of different absolute paths with the same filename. I changed my build to use the same gfortran for everything which solved the issue.

There are two things that should be improved I think:

• Show indirect dependencies in delocate-listdeps.
• Improve the error message for this situation and include the absolute paths of the two conflicting dylibs.

PR #94 should have improved situations with indirect dependencies. Can you test your wheel with the latest version of delocate?

delocate-listdeps also shows indirect dependencies since #118 was merged.
