No, don't put this path in ld.so.conf; it will just confuse apps that
are wanting gtk 2.4 in the normal paths.  Rather, before running apps
you've compiled to use /opt/gtk2.8, do:

export LD_LIBRARY_PATH=/opt/gtk2.8

add "export" to the front of that.

Yeah.

Yup.

If you wish to compile against the stock gtk install, just unset
PKG_CONFIG_PATH.  Pre-compiled apps don't care about this variable.

Yes.  All the dependencies should be built to be in the same place.
This actually don't need to be strictly true, but it makes it easier.
You might find it useful to download and use the garnome builder utility
to automate setting up the latest gtk (and optionally gnome 2.14 or
whatever).
