Uh, upon examing the ls_mysql.c source, it appears the function therein is
named 'luaopen_luasqlmysql' (note the missing 2nd underscore). Changing
this and rebuilding/redeploying fixes this error. This doesn't seem like
a nice thing to have to do. Can someone shed some light on this? Is this
because I chose to use lua51 instead of lua50?
