pkg-config crux 2.8 vs 3.0 disparity

Probably an obvious question, but still going to ask it: I have a package which calls pkg-config like so: /usr/bin/pkg-config --atleast-pkgconfig-version 0.9 Tried the above on two virtual machines - one CRUX 2.8 (32-bit), the other CRUX 3.0 (64-bit) Here are the results, which you can try yourselves: CRUX 2.8: root@crux:~# /usr/bin/pkg-config --atleast-pkgconfig-version 0.9 root@crux:~# echo $? 0 root@crux:~# CRUX 3.0: root@crux-3-testing:~# /usr/bin/pkg-config --atleast-pkgconfig-version 0.9 Partial character sequence at end of input root@crux-3-testing:~# echo $? 1 root@crux-3-testing:~# Any idea why this is so? Should I take this to pkg-config's authors? Thanks, -- Plamen Petrov
