Installing on Leopard

I'm moving my hosting from NESCent's servers to a server in my lab (running Mac OS 10.5). Having immediate access to the database structure will be helpful in continuing TreeTapper's development. Installing and configuring postgres on the Mac has taken some work. One useful site so far is here (though note that the latest version of postgres is 8.4, not 8.3). I'll post more as progress is made...
