#Bootstrap fun: #libassuan upgraded its symbols separately from its #soname in a patch-level release (with several weeks in between!)
On #ArchLinux we had upgraded to the weird version that has a soname change but no symbol change.
Since #pacman requires the library transitively via #gpgme, there now is no clean way to upgrade this without patching all consumers in some intermediate step.
(The staging build environment would otherwise have a broken pacman and thus not be functional).
