The compiler can't find the dhelper source.  It looks in your search path,  
and then at the module path.

For example, if you did:

import x.dhelper;

it would compile main.  But then of course, dhelper better be told that  
it's x.dhelper and not just dhelper :)

// inside dhelper.d
module x.dhelper;
