bob 0.6.8: build failures due to digest dependency

[Benny Siegert <bsiegert%netbsd.org@localhost>]

Hi!

First of all, congratulations for the general awesomeness of bob! Truly a 
game changer for pkgsrc builds.

However, in my latest build, I had a couple of build failures due to a 
seemingly missing digest dependency. The symptoms are always the same:

In depends.log, I see all dependencies *except* digest being installed.

In checksum.log, I see "Bootstrap dependency digest: NOT found" and a 
failure.

I attached some typical log files.

Any ideas? This is on NetBSD-current, without a bootstrap kit. The only 
non-standard setting as far as I can tell, is PKG_DEVELOPER=yes.
