PHP5: build completion message interspersed and cut off

[pete@…]

I've just installed PHP5 on a Panther box. At the end of the progress messages, I see:

---> Installing php5 5.2.3_0+darwin_7+macosx

If this is your first install, you might want ---> Activating php5 5.2.3_0+darwin_7+macosx ---> Cleaning php5

This is not a misquote; it really does look interspersed and cut off like that. I can probably grep for "If this is your first install, you might want" and find the rest of the text, though I have not yet tried that. I suppose it might be relevant that I got this in interactive mode.
