This last error message is easy: you forgot to sudo.
As 'apt-cache show libgfortran0' will tell you, the version of
libgfortran0 in Dapper is 4.0.3-1unbuntu5, so the dependency is
satisfied.
You claim to have followed the instructions, but didn't completely.
Could you do like the Ubuntu README file says and try instead
sudo apt-get install r-base
(Instead of r-base-core). This works flawlessly here.
Hope this helps
