This was introduced last January with the changes to rewrite python
files to explicitly use the currently installed python executable.

The problem is with the way these rewrite rules are using a recursive
copy command. The command "cp -r foo obj/foo" works every time if the
destination doesn't exist or if "foo" is a file. However, if "foo" is a
directory the first time you run the command you create the directory
"obj/foo" and all subsequent times you create "obj/foo/foo". Exactly
what you're seeing.
I should have a fix committed soon.
