Check the values of the RELEASE, RELEASE_LAST and RELEASE_NEXT variables found near the top of the root include/data/configure.in script. Just to be safe, invoke configure to make sure that the release value is set properly in the config/config.* files.

[root@quesadilla nst]# emacs -nw include/data/configure.in
[root@quesadilla nst]# ./configure
[root@quesadilla nst]#
