Compiling a few apps at once: XFCE4 CVS

Question

Hello. I'm trying to write a single PKGBUILD to create the XFCE4 CVS version, but I've got a few problems. A lot of packages in XFCE4 depend on other packages in XFCE4. I'd like to install one package into $startdir/pkg and then I want to make the configure scripts of the other packages to find the app installed in $startdir/pkg and use it. However, I've no idea how to achieve this.
Can anyone give me a hand?

Thing is, this is a CVS version. Much easier to maintain for something that is updated every other night, at least for testing purposes.
As for the URL, I know how to build XFCE4 basically, I've already coded a program to generate every PKGBUILD for a given package name, grouping them all under xfce4-cvs. But I'd like to make it into one PKGBUILD as I find it easier for me to maintain until XFCE stabilizes.
Also, it's a rather educational question, for my general knowledge. Can you tell me how to achieve this?
technically it is possible to hack build() to use more $startdirs and then make pkgs for each, but in my eyes it is nonsense, as the principle for a PKGBUILD is to make one pkg --- what you want i think is done with "makeworld" (see docs) that runs makepkg in a directory on each PKGBUILD in a subdir
also if you would hack the build() and do invest a lot of time: the trouble that will come up is: libSOMETHING is often a dependency to SOMETHINGELSE, and therefore you cannot build them in one pkg (as the libSOMETHING must first be installed before you can compile something against it) --- if you want to save you time, make a local repository (see docs) and add xfce4-cvs to it and then when you run makeworld in this directory, it will build you the pkgs - then "gensync" and then (when the local repo is in pacman.conf), the next time you run pacman -Suy, it will ask you to update your xfce4-cvs pkgs, as in your local repo, they are updated [this as an alternative to pacman -U pkgname.pkg.tar.gz for every pkg that can be boring]
