Trying to build pgadmin

I recently decided to look into the possibility of doing some hacking on
pgadmin to add some features/fixes that I've wanted. I'm trying to
build pgadmin on OS X (10.6 Snow Leopard) using the EnterpriseDB
Postgres Plus distribution and the latest svn checkout. I followed the
instructions for OS X to the tee, I set the PG_HOME variable to
/Library/PostgresPlus/8.3, but I still got configure errors complaining
about the postgresql directory not being present. I even tried passing
in the --with-pgsql=DIR parameter, but it didn't make any difference.
I'm stumped, because far as I know, I have all of the necessary
libraries to build pgadmin with the stock install of snow leopard and
the enterprise db install. I suppose I could download all the complete
source trees for WxMac, Postgresql, libxml, etc, but I'm trying to take
the easiest route first.

Below is the output of the configure command. Any help would be greatly
appreciated.
