There is an informative section on the Programming Ruby online book:

http://www.rubycentral.com/book/ext_ruby.html

Should be a good introduction to embedding the interpreter in your C 
program. It appears to do everything you're looking for.

Not clear what you mean by "modules", most modules dont have to be built, so 
if you dont want them just delete the "lib" directory.
