hwdb is for:
sys-fs/udev: read vendor/device string database and add it to udev
database
Evidently, if zlib is enabled then a file which udev needs to read to pull the
vendor/device string will be zipped up and udev can't unzip or read it.

Yeah but this error just occurred and I haven't recently installed anything
which should have caused it, so I'm trying to figure out why the change. You
can specify use files for one package but it's not usual, at least to my
knowledge, just to get common packages to both be installed.
I went the other route and disabled hwdb.
