Its bundled in my research project, Babel, version 0.10.*.

I use it to mix, C, C++, F77, F90, Java, & Python in a single address space
(no messaging or interpreted middleware). We run on Linux,
OSX, AIX, and maybe still Solaris.  Make check takes hours!

This is roughly what I did.  However, I only did the minimal possible
to get it to work for me (I was crunching for a release).  You may
want to review my changes... my understanding of libtool isn't *that*
