This is an issue with the g95 Fortran runtime. The easiest way around
this is to build Sage using the system's gfortran - see README.txt in
Sage's root directory. I have planned to get rid of binary g95 support
for Linux for a while, but I haven't gotten around to it yet.
Note that unless you know what to get rid of it is easier just to
rebuild Sage from sources in another directory. What needs to be
deleted is the gcc 4.0.3 runtime, but then you will likely have to
rebuild each spkg depending on Fortran as well as their dependencies,
so a fresh build is likely to be much trouble and less of an
intellectual exercise :)

R's html help is probably working in Sage, but I have not tried to do
so.
