xz and gcrypt support affect libsystemd (sd-journal)'s ability to read compressed/sealed files. Reproducible: Always
Please describe an actual problem. Like a couple of steps or a configuration that has certain undesirable consequences.
This is a good catch. I was wondering about some of these library deps when I was working on on systemd-215. I suppose we should review the others to see if they affect libsystemd as well.

A quick grep HAVE_ didn't find anything. I looked in: src/resolve src/systemd src/libsystemd src/journal There is lz4.
Alright, I'm calling this solved then.
