Yes. You'll need Ice 3.3.0. What OS are you using?

ParametersI is in trunk. The documentation on the wiki is slowly
moving to match Beta4, and the *most* Beta4 is OmeroClients since it
is being written currently while we port all the clients.

In the Beta3 line, where blitz is not turned on by default, it's
necessary to edit:

  etc/local.properties

and add the values:

  no.ice=false
  ice.home=<The top-level Ice directory with slice subdir>

These instructions (which haven't been updated to Beta4 yet) are at:

  http://trac.openmicroscopy.org.uk/omero/wiki/BlitzBuild

Once you have the right Ice version and the configuration above:

 ant 

which calls build-default should suffice to build blitz. At that
point, you might want to take a look at:

  http://trac.openmicroscopy.org.uk/omero/wiki/OmeroGridInstall

for getting the server up and running. Let us know what else would
help.
