Ignore any differences from the description regarding the directory
structure. Things are probably a bit outdated.

Actually, you have to put the jars into the "_SharedLibs" directory.
Unfortunately, the readme has a wrong naming scheme compared to what the
build file actually says. Note the 's' in "_SharedLibs" and the
different ANTLR-jar name. I'm using a depot version of the build file
where there may other changes compared to the 3.0-version, so you may
end up editing files yourself again, if I'd sent it to you.

The files should be in the source distro (except the nant stuff).

I hope I was helpful enough. :)
