This fails… See here:

The previous tests were made by the MacPorts package manager which creates a somehow own environment. It can be shown when running it in debug mode.
BTW, I had the diffutils uninstalled and reinstalled them for test. The reason for uninstalling is here (Tcsh alias newly created to use gdiff instead of old original Apple diff):
root 403 /\ alias gdip 'gdiff ~/Portfiles/Portfile-\!{:1}-312 `port file \!:1`'
root 404 /\ gdip mupdf
gdiff: program error
gdiff: program error
Abort
root 405 /\ l ~/Portfiles/Portfile-mupdf-312 `port file mupdf`
-rw-r--r-- 1 root admin 5395 14 Mai 11:45 .../macports-ports/graphics/mupdf/Portfile
-rw-r--r-- 2 root wheel 5187 12 Apr 09:31 .../Portfiles/Portfile-mupdf-312
Executing the tests of the just built software starts with:
#!/bin/sh
# small examples
. "${srcdir=.}/init.sh"; path_prepend_ ../src
so the actual test
echo a > a
echo b > b
for opt in '' -u -c; do
returns_ 1 diff $opt a b > out 2> err || fail=1
# Remove date and time.
sed -e 's/^\([-+*][-+*][-+*] [^ ]*\) .*/\1/' out > k; mv k out
compare exp-$(echo $opt|tr ' ' _) out || fail=1
done
should be using (g)diff just built.
Trying to run 'make check' from the sources' root directory does not show any progress, so maybe I need a pristine build for testing…
