That's about as far as I could decipher myself, thanks for confirming my 
assumptions.

So the question morphs into:
- At what moment during package installation are the script directories 
added to the search path?
It looks like having PKG_ADD in the script directory should work, but on 
my win7 box it doesn't.

...and it looks like some other contents is copied into those 
PKG_ADD/PKG_DEL files as well (forgot where I saw that code, perhaps in 
load_path.cc).
