Wow, you're right! Never checked that myself with --version :-\

That's...even more confusing. I always thought binaries in /rescue are the 
statically linked counterparts of things in /usr/bin. But it's indeed a 
different version!

So, if /usr/src/usr.bin/grep/ is building the FreeBSD version, where is 
the (old) GNU grep version built from? Ah, and I just found it:

 $ cd /usr/src/external/gpl2/grep/
 $ make
 $ echo foo | ./bin/grep --devices=skip foo || echo FAIL
 FAIL

Bingo!

Hm, there's also textproc/bsdgrep-devel in pkgsrc, maybe that could be 
moved to /usr/src/external/gpl2/grep. 

Anyway, thanks for responding!

Christian.
