Yes, make install wouln't do some stuff that is specific to what is done
in debian/rules. Anyways, I'm surprised about the java compiler that is
not available on Alpha... the package builds fine on buildds, so this
definitely means there is one.
If you don't want to build java stuff, you can also still use
debian/rules binary-arch.

Haven't tried. But there is definitely something wrong going on in gcc
when it compiles the url-classifier component with optimization.
