[Serusers] mysql.so

Hi, I have downloaded ser-0.9.4_src.tar . After compiling we found that mysql.so is not created. When I try to compile this module separately it gives error that mysql.h file is not present and when I check in modules/mysql, it is not present. How to build mysql.so module then ?
