Correct. My assumption is that the environment MacPorts creates to build/install/test software is quite different.

It is this executable:
tiger pete 224 /\ l `which gdiff`
-rwxr-xr-x 1 root admin 221052 20. Mai 10:40 /opt/local/bin/gdiff
Months ago I had uninstalled diffutils because gdiff did not work correctly. And to perform some tests I decided that it would be best (most simple) to install them again…

OK, here is the test with exactly the diff executable built some hours ago:
tiger pete 227 /\ /opt/local/var/macports/build/_Volumes_BSD-Linux_macports-ports_sysutils_diffutils/diffutils/work/diffutils-3.12/src/diff a b
