See sage/setup.py (search for "packages"). Put your directory in there. Also, make sure you have an __init__.py and an all.py in your directory (see other directories for what should be in these files). This may be more than you need, but it should work, probably. If you have a Cython file, you also need to add it to sage/module_list.py.
