Are you running chroot perhaps?  If so, the path would need to be relative 
to your chroot.

I have a pipe backend working, all my config has is:

pipe-command=/home/dns/bin/pipe.pl
pipe-timeout=2000
pipebackend-abi-version=2
pipe-regex=^([a-z0-9]|-|\.)+\.[a-z]{2,7};(A|ANY|TXT|MX|NS|SOA)$

I would highly recommend the regex; I had problems with real garbage getting 
through to the pipe backend without it, DNS queries with linefeeds and 
other crud in them for example which really messed up my backend.  Other 
than that, I found the documentation fairly minimal but enough to get it 
running.
