Thanks!

Right, I think I see the problem.  sratom's pkg-config file has this
line:

  Requires: lv2 serd-0 sord-0

Which means that these need to be available when build systems run
e.g. 'pkg-config --cflags sratom-0'.  This is the most common use of
propagated-inputs in Guix.

I went ahead and propagated these from 'sratom', and removed the 'lv2'
and 'sord' inputs.  Let me know if you think something is off!

Right.  Header files are usually architecture-independent, so having
them as native-inputs should be safe.

Applied (with the dropped inputs), thanks!
