I can't seem to get the code to compile on OS X, using Macports for the dependencies. So far, configure is complaining about not finding the PROJ.4 install directory. I have installed postgresql90, postgresql90-server and proj with the -k switch to keep the source code (I actually reinstalled proj with "sudo port -kf upgrade proj", which I think reinstalls and leaves the source code - please correct me if I am wrong).

Yes it does, but it would also rebuild all of proj's dependencies, if it had any. It doesn't, so you didn't experience this, but for future reference, if you're going to use the -f flag to force a port to rebuild, you almost certainly also want to use the -n flag to tell MacPorts to only rebuild this port, not also all of its dependencies.

If you look in the existing postgis (1.5.2) portfile you'll see it uses the configure argument:

--with-projdir=/opt/local

https://trac.macports.org/browser/trunk/dports/databases/postgis/Portfile?rev=72647#L51

I wouldn't expect you to need to keep the source of any of the dependencies, but merely to have the compiled result installed into prefix /opt/local.
