And while I am at it ... perl seems to be missing, too.

Sigh, alex is not supposed to depend on Happy because it comes with the Happy-generated files. But this functionality in Cabal seems to break all the time. Let me check and see what happened.

Cabal should have never attempted to regenerate the parsers if build-tools: happy is not specified

Do you mean "should" as in "it doesn't behave like that right now, but someone should fix it", or "I believe it behaves like that now, so if it doesn't it's a bug"?
If Cabal never runs Happy unless build-tools: happy is present, then I would need to have a -f devel flag to alex to enable the build-tools: happy line when modifying the parser or building the source distribution.
