Hi David,

Here is a more ubuntu-specific answer:

14.04 has tachyon of the appropriate version in the standard package
manager, but please make sure you have both libtachyon-0.99 and
libtachyon-dev (this is the package with the .h files) installed. With
this installed, you will need to edit the configure script somewhat, as
that is what tells the compilation where to look for headers and
libraries. Here is what I have on 14.04:

$libtachyon_defines = "-DVMDLIBTACHYON";
#$libtachyon_dir = "$vmd_library_dir/tachyon";
$libtachyon_include = "-I/usr/include/tachyon";
$libtachyon_library = "-L/usr/lib";
$libtachyon_libs = "-ltachyon";

Now if you reconfigure, the make process will progress further.
