Comment (by concert):

 I think I am seeing the same issue via a slightly different route.
 I've got a package that builds and binds some C and sets `extra-lib-dirs`
 in its package.yaml.

 In a module depending on it I get the "can't load .so/.DLL" error when
 using template haskell (or in my case quasiquotes).

 The library I depend on to trigger is here (you will need meson to build
 it):

 This may be packaged wrong, being my first stab at something like this.
