One of the things that I really dislike about homebrew is its refusal to run via sudo plus the requirement that you own /usr/local.

This means:

1) It is a security hole; any application can now modify system-wide applications at any time.

2) You can't have multiple users able to use homebrew.

I was expecting homebrew to be something similar to apt/yum/etc, but this makes it pretty fundamentally different.

How does Macports handle this? Does $USER still need write access to /opt?
