Just out of curiousity, I did the following:

[stathis@archlinux ~]$ cd /usr/lib/
[stathis@archlinux lib]$ sudo ln -s libgfortran.so libgfortran.so.1
[stathis@archlinux lib]$ R

[ ... ]

I haven't used R for the last 2 weeks, so I can't remember what packages have been updated in the meantime.

Thanks a lot
