Symlinks are not resolved properly to check location.

	_normalized(prefix) for prefix in self.base_paths["libdirs"].split(os.pathsep)

The path is never resolved if it is an absolute path with symlinked parts. It is often the case with Linux, where the virtualenv home is symlinked to ~/.local/share/, then dist_is_in_project will always return false.

Remove the is_absolute check in _normalize funciton can make it work.

More info FWIW: I have virtualenvwrapper installed and WORKON_HOME set to ~/.virtualenvs
