~/.local was added to *be the standard* for easily installing python
packages in your user account.  And it works perfectly on the other
major OSes, no twiddling of paths anymore.  I understand the desire to
not conflict with the system's python intall (and, in fact, applaud
them for using python).  Indeed, on linux, I do end up conflicting
between my system numpy and my SVN install in ~/.local, and I don't
have a problem with it.  This comes with the territory when I start
doing power-user/developer tasks. It just to me seems odd that the OS
that works so hard to make so many things easier makes this *more*
difficult.
