errors in compiling R-2.5.0 and R-2.4.0[sec=unclassified]
...Right now I am using an older version of R, R-2.1.0 which did not
produce any error during the `build' and `install' stage, however, the
recent versions have some problem. R-2.5.0 installs and builds fine on
its own. Any insight to this problem will be hugely appreciated.
