No, it's not necessary. I just don't know _why_ it is painful. Could you 
explain it? Then I'll remove the suggestion of using AUTO_MKDIRS from 
pkglint and document its downsides in mk/install/install.mk.

My current impression is that updating a package is always painful when 
the directory layout changes. Whether you have to edit the Makefile or 
the PLIST or both. So how does a package upgrade look like if:

1. AUTO_MKDIRS is used

2. INSTALLATION_DIRS is set

3. Some other alternative I forgot?

Thanks,
