Building OpenJDK libraries using IcedTea Project for JamVM

[Roman Davidenko]

Hi, 
following your suggestions I managed to buld JamVM / IcedTea.But I would like to have a separate directory for the buld, so:
../icedtea-2.5.3/configure --prefix=/var/www/jamvm-2.0.0 --enable-jamvm ...
make
then
[root at tawzee icedtea-build]# make installmake: Nothing to be done for `install'.
Also, I'd like to do the same with CACAO, but can't get the CACAO's current snapshot. Where is it?
AppreciateRoman
