Ah thanks.  That generated a few warnings but make a configure script:

    libtoolize: copying file `./ltmain.sh'
    libtoolize: You should add the contents of the following files to `aclocal.m4':
    libtoolize:   `/usr/share/aclocal/libtool.m4'
    libtoolize:   `/usr/share/aclocal/ltoptions.m4'
    libtoolize:   `/usr/share/aclocal/ltversion.m4'
    libtoolize:   `/usr/share/aclocal/ltsugar.m4'
    libtoolize:   `/usr/share/aclocal/lt~obsolete.m4'
    libtoolize: Remember to add `LT_INIT' to configure.in.
    libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.in and
    libtoolize: rerunning libtoolize, to keep the correct libtool macros in-tree.
    libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

    configure.in:351: the top level

The configure script generated some warnings too:

    configure: WARNING: No GNU_LIBTOOL found, skip pre-building libcc-based libraries
    configure: WARNING: No GNU_LIBTOOL found, using "libtool" as name.
    configure: WARNING: libcc.fs won't work until you have installed (GNU) libtool.
    checking ffi.h usability... yes
    ...
    checking for swig... /usr/bin/swig
    swig error : Unrecognized option -forth
    Use 'swig -help' for available options.
    configure: WARNING: *** Swig without -forth. The library bindings cannot be built.
    config.status: WARNING:  'engine/Makefile.in' seems to ignore the
    --datarootdir setting

I do remember your saying something about needing a special version of
swig, but don't see the post right now.

Finally, make failed:


    $ time make -j4
    if test -r version && test x'0.7.9_20151126' = x`cat version` ; then true ; else echo 0.7.9_20151126 > version ; fi

As mentioned, if you want an account on the box I'd be happy to put one
on for you.

That is great!
