new module builds

Hello, Previously I created a new module for accounting. I'm now trying to iron out the production build process. Starting from a fresh untarred src (2.2.0) distro, what files do I need to drop into src/modules/rlm_mymodname? I placed config.h.in, configure, configure.in, Makefile.in, and rlm_billmax.c, then did <rootdir>./configure; gmake but the new module was ignored (not built out). What am I missing? Bill
