Probably because of an old version - see below.

The 'match' function in string lib was introduced in Lua 5.1 - minimum
required for RRDLua -, so it seems you have 5.0 or older. And I have a
broken code to check Lua version... Sorry for that, I'll fix it and send
a patch.

BTW, is there a standard way to check version in autoconf?  I'm just
starting to play with autoconf.
