The g77 packages used to provide a g2c-pic library. E.g. when 1.8.1 was
built, they did and thusly the Depends ended up in /etc/R/Makeconf. However,
on your current system, g77 no longer provides the library -- so this fails.

You need to bring R and g77 back in sync. There are several possibilities:

a) install the current r-base-core and r-base-dev packages from unstable
b) recompile the 1.8.1 package locally to reflect to reflect your current
   compiler setup
c) edit /etc/R/Makeconf  

I'm sorry for the bug, but these things are hard to control for.
