Follow the "source code" link on the left and you'll get instructions
on checking out rhug.

Yes, you can do that. In some cases the rhug versions are modified to
build from source with gcj (i.e., work around gcj bugs, sigh). Also
sometimes parts are removed when libgcj doesn't have the required
library coverage... e.g., if a package uses com.sun.*.

 gcj -shared -o libfoo.so foo.jar
This won't always work if required packages are missing from libgcj.
Unfortunately this happens from time to time.
