[Rd] package gsl assumes incorrect gcc version during install (PR#10451)

OS: Ubuntu Gutsy
Submission from: (NULL) (206.248.157.88)


I installed libgsl0-dev then tried to install the gsl cran package,
unsuccessfully (see output below).  As a workaround I created a symbolic link to
/usr/bin/gcc-4.2, ie:

sudo ln -s /usr/bin/gcc-4.1 /usr/bin/gcc-4.2

The correct behavior of the gsl package should be to use the executable
'/usr/bin/gcc' which is already linked to the current gcc version.
