+Subject: [PATCH 1/2] configure.ac: drop lua5.1 pkg-config check.
+
+The official upstream name for the lua pkg-config file is "lua.pc", so
+preferring the name "lua5.1.pc" to the official one can lead to
+problems when both are installed. Specifically, if lua-5.2 is
+installed and its pkg-config file is called "lua.pc", then ./configure
+will still detect (and use!) lua-5.1 if it happens to be installed
+with just the right name.
+
+This was honestly left in only for superstitious reasons, and now it's
+actually causing problems on Gentoo systems that have more than one
+version of Lua installed. So, time to go.
+
