Huh; you're right.  It seems to unpack correctly using the the name of the 
group, rather than the GID when I perform a simple test.

I think what must have lead me to this wrong conclusion was that in my case, 
the group would only be created by the .install script *after* the package was 
already unpacked.  Since the group didn't yet exist, bsdtar would presumably 
fall back to the GID.  So in practice, files still need to be chowned in the 
.install script if they'll belong to non-standard groups, but not quite for 
the reason I thought.

Thanks for highlighting this.
