Stats is a base package, so that won't work.  Base packages are built 
and installed differently from other packages.

He could modify the sources and build a custom copy of R for himself, 
but that seems kind of extreme.

A better way would be to copy the source for the function into his own 
package.  If he intends to release it, he must retain copyright notices 
on it and release his own package with a GPL-compatible license.
