I am assuming that MacPorts base copies these files to the sip-workaround directory when it thinks they are being used.

I note that macOS (High Sierra at least) ships with both /usr/bin/perl and /usr/bin/perl5.18. They are both version 5.18, their "-V" output is identical, yet the files have different sizes. I am uncertain why this is. I would have thought one would be a symlink or hard link to the other.

I note that the openssl port specifies "configure.perl /usr/bin/perl". Presumably this means that /usr/bin/perl gets used, and presumably MacPorts has copied it to the sip-workaround directory. I am uncertain why darwintrace thinks that /usr/bin/perl5.18 is now needed.
