There is pkg_chk, but if you don't have a pkgchk.conf it is hard to 
recover from errors.

I wrote a script that should make it simpler:

The script uses pkg_tarup to backup packages before doing anything else. 
You have the chance to go back to your previous state by installing the 
backup-packages.

Agreed. However, that does not solve the one big design-flaw in pkgsrc:
to build a package you need it's dependencies installed. Maybe it's 
possible with pkgviews somehow? Install the new stuff and delete the 
older packages only if everything worked?
