I doubt that you will find what you are longing for, but: There is a Windows
version available at the "Homepage of the drep package" at
<http://math.uprm.edu/~edgar/dprep.html>.
This version 2.0 can be loaded without errors into R 2.8.0 though it appears
not to be fully compliant with the tests on CRAN.
