A couple days ago, I had this failure when building 
security/p5-Digest-SHA1 on DragonFly:

Makefile out-of-date with respect to 
/home/reed/pkg/lib/perl5/5.8.0/i386-dragonfly-thread-multi/Config.pm 
/home/reed/pkg/lib/perl5/5.8.0/i386-dragonfly-thread-multi/CORE/config.h
Cleaning current config before rebuilding Makefile...
/home/reed/pkg/bin/bmake -f Makefile.old clean > /dev/null 2>&1 || /bin/sh 
-c true
/home/reed/pkg/bin/perl5.8.7 Makefile.PL "INSTALLDIRS=vendor"
Checking if your kit is complete...
Looks good
Writing Makefile for Digest::SHA1
==> Your Makefile has been rebuilt. <==

false
*** Error code 1

Stop.
bmake: stopped in 
/build/reed/tmp/pkgsrc/security/p5-Digest-SHA1/work.reed/Digest-SHA1-2.11

I didn't look further. I was actually installing pkglint. So I did the 
"make install" again, and it continued fine.
