+Subject: Check for either xfont.pc or xfont2.pc
+
+More recent versions of Xfont have a different API (with namespacing
+for libXfont functions.) Check for xfont2.pc and if found, use that, and
+use the new API. The rational for preferring libXfont2 is that as a recent
+change the xserver module looks for and requires libXfont2, and it's better
+not to have both versions of the library in process.
