A complete (absolute) pathname begins with a slash. In your definition
of PKG_CONFIG_PATH, the first / after the = is part of the first
pathname, not part of the syntax for the variable definition.  A
directory usr/X11R6/lib/pkgconfig probably doesn't exist, whereas
/usr/X11R6/lib/pkgconfig probably exists and contains .pc files. You
need leading slashes on every path in PKG_CONFIG_PATH, not just the
first one.
