It's a problem if you need the (very probably better) core octave functions.
So it depends on the situation.

A week or so ago I started looking if I amend fix pkg.m so that octave-forge
m-files that will shadow core octave functions can automatically be skipped
(at the user's discretion, of course).
Ben & John helped me with some code snippets, I think I found where to patch
pkg.m, but I got distracted :-(  (happens often to me these days)

I'll try to get further with pkg.m this weekend.
