I thought this was going to take hours, but it took just a few minutes! There were some hints that it was related to namespace::clean or namespace::autoclean, so I checked the Moose install output for "clean". I found only the following: 

[...]
  CPAN.pm: Going to build D/DO/DOY/Package-Stash-0.23.tar.gz

***
    Conflicts detected for Package::Stash:
      MooseX::Role::WithOverloading is version 0.08, but must be great
+er than version 0.08
      namespace::clean is version 0.18, but must be greater than versi
+on 0.18

Checking if your kit is complete...
Looks good

There were no corresponding installation of those dependencies. Upgrading namespace::clean fixed the installed version of MooseX-Types that got broken, and allowed me to install 0.25 cleanly.
