Re: installation prefix with pkgsrc including non-BSD: always /usr/pkg?

There is a distinction between things that have been installed by
pkgsrc and things not installed by it, which are considered as
belonging to the operating system, or "built in". See the section on files in the pkgsrc guide.

Consider everything outside your pkgsrc PREFIX (in this case /usr/pkg,
I think) as belonging to some sort of "base system".

This does not matter, as the two don't mix.

I think that you are confusing a few things here. First of all, you
cannot (generally speaking) mix Slackware and pkgsrc packages under
the same PREFIX. The question is not whether you can "upgrade" a
Slackware package with a pkgsrc one or vice versa. The pkgsrc
installation prefix, the package database and the contents of the
packages are self-contained, with the exception of basic libraries
such as libc and the stuff. pkgsrc packages do not depend
on Slackware packages, and they are not the same thing.

Think of pkgsrc as a separate entity from your base system. Your best
bet would be to install a small Slackware system and take the rest
from pkgsrc. If you already installed, say, gtk+2 in Slackware, you
will have to install it again in pkgsrc to use packages depending on

Did I make myself clear?
