[Haskell-beginners] Why is cabal trying to install a particular dependency?

Sometimes I want to know why installing package X will require package Y.
After a lot of recursive manual inspection of .cabal files and --dry-run, I
discover that X depends on A, which depends on B, which depends on C, which
requires Y unless some flag is specified.

Is there a way to ask cabal to tell me this?
