Seems to have it as perl-Search-Xapian, which provides Xapian.pm.

Well, this is for toolbox which uses podman, not docker. Toolbox is actually
the preferred mechanism in Fedora for setting up quickie work environments,
especially on something like Fedora Silverblue with its immutable root
partition.

I don't intend these instructions as the preferred mechanism for getting lei
up and running, just to be clear. Eventually, it will be packaged for most
distros -- but for now it's a convenient way to get the latest version on the
platform most likely to be most tested (Debian).

Yeah, some of these were mostly for "make test" runs and others are adding
basic packages to the container image to make it slightly more usable (I don't
like nano or whatever is the default editor in the container image).

All noted -- I may be the one who packages things for Fedora at some point, so
this is useful info.
