I noticed that the output does not refer to zlib:

$ guix gc --references $(./pre-inst-env guix build msgpack)
/gnu/store/8m00x5x8ykmar27s9248cmhnkdb2n54a-glibc-2.22
/gnu/store/jh52sklgbvq5f0z637wr99a64y25cx8r-msgpack-1.4.1
/gnu/store/v39bh3ln3ncnzhyw0kd12d46kww9747v-gcc-4.9.3-lib

However, the compilation fails without it.

We need to make sure that msgpack can find zlib at run time. Lukas, can
you check if there is a build-time configuration option to provide the
path to zlib?
