 asl failed to build:

 icu-devel was just updated to 74.1. icu is still at version 73.2.

 Nothing in asl's dependency chain depends on icu-devel. (I can't find any
 port that does.) Yet apparently icu-devel, not icu, was active.

 The build preceding this one] is where the commit that updated icu-devel
 was handled. icu was deactivated, icu-devel was built.

 Is this a bug in mpbb? libxml2 depends on `path:lib/pkgconfig/icu-
 uc.pc:icu` so icu-devel satisfies it but since icu's install_name keeps
 changing with each major release it's not really a drop-in replacement.
 Maybe mpbb should ensure that the default dependency (in this case icu) is
 active, and not one of the path-based alternatives?

 Or is the bug that ports like icu whose install_name keeps changing should
 not be depended upon using `path:`-based depspecs?
