Hi Bob,
This is annoying because fixing this will most likely require a new release
of liquidsoap which will have to wait.
What I would recommend for now is to switch to a previous version of the
compiler. I believe that 4.04.2 should be just fine. opam makes it very
easy, just do:
% opam switch 4.04.2
% eval `opam config env`
% opam install liquidsoap (and other packages)
