Comment(by sorin.sbarnea@…):

 when I installed latest release of MacPorts (10.8.2) on OSX 10.6 it did
 not update the path. Also please be aware that we expect to change the
 paths for all *users* not only current user, specially because on OSX most
 users are not using root account.

 I think that appending to /etc/paths is a *good* and *safe* approach. I
 did not find any issues by having the macports paths to the end of the
 path.

 Replacing OS utilities is risky and can break other OS components on OS X
 so using MacPorts too *add* missing utilities should be the default. If
 somebody really wants to replace them he can change the order. Also the
 installer could inform the user about this.
