That's not enough. You also need to explicitly compile that module and 
specify the .o file on the DMD command line (or specifying the .d file 
on the command line to compile it anew every time).
A tool like bud/build or rebuild will do this for you automatically, see 
http://dsource.org/projects/build or 
http://dsource.org/projects/dsss/wiki/Rebuild, respectively.
An alternative option would be to manually compile all the stuff that 
build-*.{bat,sh} doesn't and pack it into a library to specify on the 
command line. That may for instance be helpful with IDEs that aren't 
aware of the build tools I mentioned above.

No, I don't think that would cause this particular problem. However if 
you didn't install Tango correctly that may cause some other problems 
later on.

As mentioned above, I'd suggest using either bud/build or rebuild to 
compile your programs.
