Here are the interesting bits from two runs of the code I just posted. The top results doesn't try to install Expect because I remove it from the code. Everything works. After "Delayed until after prerequisites" it continues into rematin() and eventually to expand_by_any(), which expands Devel::Symdump.
In the second one, which is the same code tries to install Expect and gets a distroprefs hit (as in the output in the last message). After "Delayed until after prerequisites", it gets to expand_by_method() and doesn't go any futher. Again, I'm still investigating this, but even explaining it on a mailing list might help. :) [13:27:45]: ---- Unsatisfied dependencies detected during ---- [13:27:45]: ----
