Hi. Looks like the file /usr/lib/python2.2/config/Makefile is missing, which
is very strange if you compile it from sources, as you told me in another
message. Could you check the directory /usr/lib/python2.2/config to see what
it contains?

Have you build from the standard sources (from python.org), or from sources in
the mandrake distro? I suggest the first.

Although, as Tim said, you will need to rebuild R as shared lib, so I suggest
also to download the R sources from www.r-project.org.

It should build fine with that packages.

Hope it helps,
