I have two ocaml projects being compiled with ocaml 4.02.1. Is there a way to create separate opam installations for each project instead of having both projects install their dependencies in the global 4.02.1 opam switch?

In opam you can have several installations of the same compiler:
opam switch -A 4.02.1 proj1
opam switch -A 4.02.1 proj2
will create two separate independent stacks for each project. You may also find these commands useful:
opam switch export
opam switch import
