I noticed the following today: nell:/private/etc barnes$ locate periodic | grep bin /opt/local/bin/periodic /opt/local/var/macports/software/openmotif/2.3.0_2/opt/local/bin/ periodic /opt/premp/bin/periodic /opt/premp/var/macports/software/openmotif/2.3.0_2/opt/local/bin/ periodic /usr/sbin/periodic nell:/private/etc barnes$ sudo which periodic /opt/local/bin/periodic this is, of course, due to the prepending of $PATH by macports (1.6.0) in .profile: # Your previous .profile (if any) is saved as .profile.mpsaved # Setting the path for MacPorts. export PATH=/opt/local/bin:/opt/local/sbin:$PATH I believe the 'periodic' commands of openmotif and /usr/sbin are extremely different ;). Is this sort of thing known/expected? Are there other conflicts with system commands? Or is this perhaps an openmotif port bug? Just curious. thanks, Brian
