On a fresh 2.0.2 system with a new pkgsrc, there are two obvious bugs.

One: after installing pkg_install, nothing will install before digest is 
installed. digest is not installed with pkg_install, nor is it listed as 
required for other packages. People new to pkgsrc would not know this, nor 
that they'd be required to manually install digest.

Two: after doing a "make install" in a directory, doing a "make update", 
even if that package is not installed (for instance, if it was deleted or 
if the "make install" was done in a chroot) basically does a "make clean", 
but does not install the package.

Thanks,
John
