You'll need to edit PATH to (temporarily) to not prefer the MacPorts prefix. echo "$PATH" With this information, re-arrange the values like so: PATH=/usr/bin:/usr/sbin:...:/opt/local/bin:/opt/local/sbin ./macbuild.sh Where "..." means anything you have in-between. If you also have /opt/local/libexec/gnubin in there, move it before /opt/local/bin. Mihai
