It is only in CVS because Altera did not submit their tools port to
the FSF.  We can only put ports in standard distributions that we
can provide tools for.

So you will have to work from CVS and build your own tools from
source.  The port was used fairly recently and worked fine.  But you
have to build your own tools.

Look back in the mail list archives for the last persons who posted
on this.  Email them and myself privately and we should be able
to get you the tools and patches.
