help compiling pgmanage

I'm doing a little research in order to find a suitable sql manager to use
with postgresql

I'd like to give a try to pgmanage but I can't compile it (If anybody can
pass me a compiled version for windows it would be great)

I've pgmanage.tar.gz and I'm trying to compile them on windows, but I think
that these files are for linux.

I've installed Java runtime Environment SE 1.4.2_10 and the Java 2 SDK SE
1.4.2_10

But I can't find the ant make utility anywhere (I though it should come with
the SDK)

So I tried to compile it with linux

I'm using gentoo

tux pgmanage-src # uname -a
Linux tux 2.6.13-gentoo-r5 #3 Sun Oct 30 03:07:18 ART 2005 i686 AMD
Athlon(tm) XP 2600+ AuthenticAMD GNU/Linux

And I have installed blackdown-jdk-1.4.2.02 and blackdown-jre-1.4.02

And this is what I get

----

tux pgmanage-src # ant all

pgManage.pgManage

Any idea???

Or perhaps I should try with sun's virtual machine?
