Can't load .so/.DLL error when building in stack 2

Possibly related to #3559 .

Got a hard-to-debug error message from stack 2. The project builds fine in 1.9.3 but fails on 2.1.3. The `comp-crypto` package contains crypto libs, which are found by the `globalstate-types` pkg in 1.9.3 but not in 2.1.3.

Dependency chain: lang -> globalstate-types -> comp-crypto.

I expected this to work out of the box, but it doesn't. Secondly, I expected an error message I could understand.

# build-failure 2.1.3
`stack-2.1.3-osx-x86_64 install --fast`
