Citando Paul Guyot :
I don't understand either. port -t configure works perfectly fine here. Could you please send us the output of the command on your box?

In fact, I have found what the problem was: at first, I had named the package docbook2x, then to fetch more easily, I put the x in uppercase, but the directory ~dp/build/_Users_manu_Vrac_dp_textproc_docbook2x/ was still there, which triggered the out of sandbox problem. But since it is case insensitive, everything was working OK outside of trace... And I thought port clean --all docbook2x would have suppressed it, but apparently, it does not. Thanks for the answer, Emmanuel
