Thanks for your help guys.
Tim: I had already seen RPy; but its Windows binary is compiled against
Python 2.2 (and I have 2.3) so it didn't work.

Uwe:
(1) I installed Active Perl (it seems to be needed by Rcmd INSTALL)
(2) I then created a tar.gz with the modifications found in INSTALL.WIN
(3) Here's what I got:

E:\to_do>Rcmd INSTALL -c e:/to_do/RSPython.tar.gz

---------- Making package RSPython ------------

   **********************************************
   WARNING: this package has a configure script
         It probably needs manual configuration

  installing inst files
A package must contain a DESCRIPTION file
make[1]: *** [frontmatter] Error 27
make: *** [pkg-RSPython] Error 2
*** Installation of RSPython failed ***
make --no-print-directory DLLNM= RHOME=C:/PROGRA~1/R/rw1080 BUILD=MINGW \

C:/PROGRA~1/R/rw1080/src/gnuwin32/MakePkg clean
make: *** [pkgclean-RSPython] Error 255

What's a description file? Any suggestions compiling this?
Thanks again in advance,
Hector
