I think the question was how to avoid to pollute the source tree.
And the answer to this question is to write a makefile that provides a 
mechanism to clean up after installation - or at least a "make clean".

For myself: For packages I am using the mechanism Andrew descibed at 
first (building at first); for building R, I am copying the source (svn) 
tree and "make"ing from the copy.
