 Apple's dyld is giving a misleading error message (failing to distinguish
 the dylib id - the same string as a file path - from an actual file path),
 which is a bug.

 And when it does so, it could warn you that your configuration is broken
 so ports it installs can't be expected to work.  When it scans for linking
 errors it could check against DYLD_LIBRARY_PATH, predict what the
 misleading error messages will be, and clarify them individually.
