importPath ".." causing excessive build times

This causes issues when building an application that depends on ae from Nix: the ae library will have been added to the Nix store (/nix/store/…) but because of the importPath "..", dub will iterate all files and folders in the Nix store. This is often 20GiB worth of packages, and doesn't complete (I aborted after 5 minutes.)

Yes, this is due to a problem in the Dub package manager. See commit 363227fb3953276f0d6e1c0eb2ef7d2e0118a5e6 for details. It also describes this exact problem and a workaround.
