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
