The code itself looks fine.  What's your compile command line?  Are you including both 
modules in arguments to the compiler?  Something like:
dmd test.d ooolib.d

(Not attacking your intelligence.  Its just a common first mistake.)
There's also the Build utility if you worry about command lines getting long.
