All paths in pkgsrc tree are relative, thus when you work inside the tree,
you work with current tree and everything is fine.

If you have to pass path to pkgsrc tree to some tool, e.g. revbump, you just do 
it.

If you still need absolute path to pkgsrc tree, you're most likely playing 
tricks,
but then you have to know what you do anyway.

One of such cases is when you're doing something like

  .if $(.CURDIR) == "$(HOME)/pkgsrc-local/category/package"
  CFLAGS+= -fsomething-evil
  .endif

No, it would be much better to me if configuration files that relate to
_installation_ go along with installation, that is if they live inside
prefix or related sysconfdir.

To make it clear to others, pkgsrc tree is independent of installed packages.
You can share it between different prefixes or you can use multiple trees
to work on packages within the same prefix. Unless you're playing tricks,
prefix is determined by installed binaries, it isn't remembered anywhere
in pkgsrc tree, and path to pkgsrc tree isn't remembered anywhere inside
prefix either. This gives you freedom to move pkgsrc tree around and to
build packages for several installations using the same tree.

On moving mk.conf.

The most reasonable approach I can come up, is installing default /etc/mk.conf
with this content:

.ifdef BSD_PKG_MK
.sinclude "/usr/pkg/etc/mk.conf"
.else
# Put your non-pkgsrc configuration here.
.endif

This is basically what I use.
