+Initial Package Version: 5.4.0
+Upstream Status:         Rejected
+Origin:                  Arch Linux, with some modifications
+Description:             Creates a shared liblua library, as well as
+                         removes optimization since it causes SIGBUS errors,
+                         and sets the search path to /usr from /usr/local.
+                         The initial version of this patch was created by
+                         Igor Zivkovic, before being rediffed for 5.4.0 by
+                         myself with some modifications made.
