[zorg] OPAM install for Linux Buildslaves?

[Rick Foos]

I noticed a discussion on IRC about opam/ocaml packages.

Does the opam/ocaml install need to be in place on all linux buildslaves?

Thanks,
Rick

sudo apt-get install opam
(from buildbot account)
opam init;opam switch 4.02.1; opam install ctypes.0.3.4 ounit
(This performs a number of private build and installs to the user account.)

The Ubuntu packages for this look like:
sudo apt-get install ocaml-findlib libctypes-ocaml libounit-ocaml-dev
(but these are different versions)
