Todd Gamblin fd3efc71fd bugfix: don't look up virtual information for unknown packages ... `spec_clauses()` attempts to look up package information for concrete specs in order to determine which virtuals they may provide. This fails for renamed/deleted dependencies of buildcaches and installed packages. This will eventually be fixed by #35258, which adds virtual information on edges, but we need a workaround to make older buildcaches usable. - [x] make an exception for renamed packages and omit their virtual constraints - [x] add a note that this will be solved by adding virtuals to edges		2023-05-15 09:15:49 -07:00
