Ok,
After about 2 days of working with this, I think I've isolated the problems.
1) The EAR and WAR files that are currently downloadable (4.2.2) are built against j2ee.jar instead of javaee.jar, and although Glassfish v2 has a j2ee.jar in it's classpath, it's just a dummy. To deploy on Glassfish v2 I had to rebuild against the javaee.jar file.
2) The build scripting for the glassfish build (ant clean start build-ext build-ext-glassfish) is broken in the current svn checkout. There are significant changes to sequencing necessary for the deployment to work properly.
Additionally, (and these are at least in build-ext-glassfish, but it could affect others as well)
3) The build-ext-glassfish target in the build chain doesn't use any app.server.${user.name}.properties or build.${user.name}.properties files from the original source tree if you've created them (which you need to do if you have a configuration different than Windows with the liferay source on the D drive in a specific folder). Instead, it just creates a new one with the field for the type of app.server and that's it.
Once I got the build scripts reworked, I was able to get everything installed and running. I'm trying to download a clean SVN so I can create a list of all deltas and submit them to the liferay team.
