And this broke the build on three machines -- two of them are servers,
and one is a PPC machine that wasn't for anything except for the
builds in a long time.

  raco setup:  in images
  ffi-lib: couldn't open "libcairo.so.2" (libcairo.so.2: cannot open
  shared object file: No such file or directory)

One possible way out: make it fall back to the dynamic case when
there's no cairo present.  The zo files in the distribution are all
from the main machine which does have cairo installed.  (That would
further bogosify a `compiled-' prefix though.)
