Yeah, I found that. I think what needs to be done is this:

R has a separate package management interface. So TeXmacs needs to carry the R
plugin as a "standard" R source package tarball. During the configure step,
TeXmacs should check for the existence of R. There are two possibilities:

1. R is present. In that case, the TeXmacs install should execute the *R package
installation* on the source package. It should leave the R package behind in a
documented place. Users with an older version of R who upgrade to R 2.0.0 will
need to rebuild the package. That's what happened to the original poster and to
me.

2. R is absent. In that case, the TeXmacs install should leave the R package on
the system in source tarball form and give the user instructions for installing
it when they install R.

Since it doesn't seem to be a very volatile piece of code, you might want to
contribute the R TeXmacs interface library to the CRAN repository, so someone
with R and TeXmacs can get the package that way.
