melange grinds to a halt w/ local abseil-cpp build

Using v0.15.8, which uses chainguard.dev/apko v0.19.9 (but also tested building w/ chainguard.dev/apko v0.20.0).

When I'm trying to build packages against a local repo w/ locally-built packages from abseil-cpp, melange grinds to a halt when resolving dependencies:

I've given it many hours, but it never completes. Memory usage continues to grow, and it burns CPU:
