Some applications complain about the locale:

	> stow .
	perl: warning: Setting locale failed.
	perl: warning: Please check that your locale settings:
		LANGUAGE = (unset),
		LC_ALL = (unset),
		LANG = "en_US.utf8"
	    are supported and installed on your system.
	perl: warning: Falling back to the standard locale ("C").

	> emacs
	(process:7796): Gtk-WARNING **: Locale not supported by C library.
		Using the fallback 'C' locale.

Both emacs and stow still work properly but I wonder where this comes
from.  Did I miss something during the install?

This could be related to this:

But no LD_ variable is set in my environment.
