That's what it seems, yes (I see there is code to download it on the fly).

However, I see no traces of LexActivator in the build log for amd64, so it
seems what we need here is a way to tell the build system to ignore
the library completely the same way it's ignored on amd64.

(I assume the library is an optional component, otherwise the package
should be in contrib).

Thanks.
