Hi everybody, I just downloaded the file R-2.0.1.tar.gz and followed the instruction written in doc/R-admin.html. In particular we installed for SuSe 9.2 AMD64 the following packages: gcc, gcc++, gcc-g77, Perl, te-latex, te-pdf, libpng, libbz, PCRE, Tcl/Tk, BLAS, LAPACK. After we just made: ./configure make make check make install (from root) make install-info make install-pdf Now everything seems to work properly: no problem at all! Many thanks to all of you who helped. Ciao!
