I just ran into the same issue due to symlinking an OCaml installation
elsewhere.  The OCaml compiler installation is not relocatable -- that is,
once you install it in a PREFIX, it must stay there.  This is because the
directory is hardcoded into the compiler driver ("ocamlc -where").

So I suspect the reason this failed for you on NixOS is because of the
tricks it plays with symlinks in order to have multiple simultaneous
package revisions.  I haven't had a chance to try NixOS out for myself
to verify this yet.
