Can't get this to work, see below for two attempts:

+available: [ (preinstalled = "false") & (ocaml-version = "4.02.0") ]
To Build:
atdgen
camlp4
build one: atdgen
default    Synchronizing with /home/travis/build/ocaml/opam-repository
Updating ~/.opam/repo/compiler-index ...
Updating ~/.opam/compilers/ ...
Updating ~/.opam/repo/package-index ...
Updating ~/.opam/packages/ ...
Creating a cache of metadata in ~/.opam/state.cache ...
[ERROR] 'preinstalled' has type bool, but a env element of type string was expected.
