/// This tests the expected error case when there is a mismatch between the pcm dependencies passed in
/// the command line with `fmodule-file` and whats encoded in the pcm.
/// The steps are:
/// 1. Build the module A with no dependencies. The first variant to build is A-1.pcm.
/// 2. Build the same module with files that resolve from different search paths.
/// This variant is named A-2.pcm.
/// 3. Build module B that depends on the earlier module A-1.pcm.
/// 4. Build client that directly depends on both modules (A & B),
/// but depends on a incompatible variant of A (A-2.pcm) for B to use.
