hide dependency in graphics/xpdf port

[Eric P. Scott]

Let's try that again, without the missing-hyphen typo:

.if defined(WITH_LIBPAPER)
LIB_DEPENDS+=	paper.2:${PORTSDIR}/print/libpaper
CONFIGURE_ARGS+=	--with-libpaper-library="${LOCALBASE}/lib" \
		--with-libpaper-includes="${LOCALBASE}/include"
.else
CONFIGURE_ARGS+=	--without-libpaper-library
.endif
