Before you're dead, you should know one more thing:

------- introducing: The Path: --------
A path starting with a '/' is a absolut path. Your root-dir. Top of all paths.
If not starting with a '/', it's a relative path to your current location.
-----------------------------------------
You should already have '/etc' and '/etc/ppp' and maybee even '/etc/ppp/peers'.

And you don't need to compile or install again.
