I don't know much about the gentoo ebuilds myself, and from the error
snippet, it's not apparent what's going wrong. The problem is occurring
in the native compilation step, however, so you can skip that step while
we're trying to figure out why the problem is happening if you so wish.
This can be done by passing --without-gcj-compile to autogen.sh or
configure.

To help us figure out why the problem is happening, it would be useful
if you could post the whole output instead of just that small fragment.

Very cool! :)
