Can't build

Hi,

I have cloned the pgjdbc repository on github. However, I can’t build the code following the directions:

$ ant -lib lib
Buildfile: /Users/christian/code/pgjdbc/build.xml

all:

prepare:
[mkdir] Created dir: /Users/christian/code/pgjdbc/build
[mkdir] Created dir: /Users/christian/code/pgjdbc/jars

check_versions:

check_driver:

What else do I need to do?
