Is your EDITOR or VISUAL environment variable set to something unusual? Darwinxref defaults to "vi", is vi in your PATH?

Ah! Yes, I had it set to open TextWrangler as my default editor. Changing it to vi made it run, and it looks like dyld builds now. Thanks for all your help hand-holding this darwin building newbie along. :) -- Eric Shepherd Owner Syndicomm http://www.syndicomm.com
