R seems in a very non-standard place
('/home/ogbos/R/i486-pc-linux-> gnu-library/2.8'
)
and it is likely to have been installed by compiling from the sources...
Then, installing packages from the sources is at least as comfortable, (if one
has no IT conection, one just has to download the package and everything it
depends on from friends/ internet caf?s;
this process has benn made easy for other complex softwares : cygwin offers the
opportunity to have a consistent mirror, even from Windows...; so does gentoo -
one can download a consistent list of packages , put them on a USB stick and
install them on an isolated PC...).
