>Description:
	It turns out that some ports, notably graphics/png fail in
	the installation phase when INSTALL_AS_USER is used.  This
	is unfortunate, but at least in the case of graphics/png
	and presumably a number of others easy to fix generically.
>How-To-Repeat:
	Install graphics/png as non-root with INSTALL_AS_USER=1.
>Fix:
	Patch below.

	It might be interesting to see how two pointyhat runs that
	install as a user and INSTALL_AS_USER=1 turn out -- one prior
	to this patch, one with it.
