Good news: just run
sudo apt-get install r-base-core-dbg
Most (library) packages (lib)foo now also ship (lib)foo-dbg which is provide
something close to pure magic -- just by installing these the already
instrumented gdb knows where to look for them. See, no more recompiling.
Debug symbols appear out of thin air. (I have used it only on Debian at home

It's moot as per the above but you need to either run the script to rsync
those in, or configure using
As for x11 instability, I happen to spend my daytime hours in from of
Cygwin/X connected to a few Ubuntu machines running R, and of late the
display has been unstable. I tend to blame the other software first, but
indeed, the most recent change was probably R. Did anybody experience that?

Confirmed. Dies for me too, but from Debian and Ubuntu connected to the same
display (Ubuntu 9.04).
Three out of two people have difficulties with fractions.
