No. You misunderstand. It has nothing to do with the package.

When R is built, it 'stores' its compiler version etc in the file Makeconf. The Debian (and hence Ubuntu) packages store that file for you as /etc/R/Makeconf via a link; the file is as always in $RHOME/etc/Makeconf.

This file defines a variable CC for the compiler. All you need to do is to set it back to 'gcc' from its value 'gcc-4.2'.

This really is a local admin issue (ie you need to fix it) and not a problem with R, or gsl.

If you got R from Ubuntu, file a bug report _with Ubuntu_ as they seem to have forgotten to switch from gcc-4.2 (which we use in Debian as default) to gcc-4.1 (which is Ubuntu's default).

Also note that CRAN has prebuilt versions of the current R release, ie 2.6.0, for Ubuntu Gutsy, see $CRAN/bin/linux/ubuntu

The CRAN version of R for Ubuntu is quite possibly of better quality than the distro's version.
