Compiling LuaSQL 2.1.1 on Ubuntu 10.04 for odbc

I can't get luasql 2.1.1 for odbc to compile out of the box, and I don't understand how to interpret the error. This is on Ubuntu 10.04, and unixodbc is successfully installed.

Fixed it by adding the -fPIC flag as suggested in the WARN variable in luasql-2.x/config. Thanks!
