Comment (by cal@…):

 I'm surprised the build actually uses dtrace, especially since it's
 useless without root privileges on OS X, and we do builds as unprivileged
 user.

 Is your dtrace a standard installation? What's the output of `ls -lash
 /usr/bin/dtrace`?

 And here's to random guessing: Did you by any chance put a SUID bit on
 dtrace? MacPorts' builds are sandboxed, and SUID binaries cannot be run in
 sandboxed environments. They fail with this exact error message.
 Console.app would also contain a message about this. You can temporarily
 disable the use of sandboxing by putting `enable_sandbox no` into
 `macports.conf`, but please don't keep it as the default.
