I'm not sure. Would anything bad happen if:

Scenario 1

a) user installs port foo built with MP 2.1 and thus non-empty dependency_libs in .la files
b) user installs port bar (that depends on foo) with MP 2.2 and thus empty dependency_libs in .la files
-> My understanding is this should work fine.

Scenario 2

a) user installs port foo built with MP 2.2 and thus empty dependency_libs in .la files
b) user installs port bar (that depends on foo) built with MP 2.1 and thus non-empty dependency_libs in .la files (e.g. from the packages server)
-> Presumably the installation would work, since it's a binary
-> Would the software work?
-> What if the user now installs port baz that depends on bar and has to build from source?

I think I understand what was changed in MacPorts, but I have a much poorer understanding of .la files and libtool in general.

Oh.
