Hello Lars,

when looking at the tetgen homepage, I see that they do not have a
version 1.5.1, but that there is a version 1.6.0. They hide the source
behind a form that asks for a name and an email address, but the real
place of the source code is easily reverse engineered.

I am attaching a corresponding patch; unfortunately there is no install
target, so I copy the binary "by hand" to bin/. And there is an
installed file etc/ld.so.cache, of which I do not know where it comes
from and which phase puts it into the output; it is surely superfluous?

What do you think? I see that your email address is @ufz.de and that the
github origin you provide belongs to ufz, so maybe you maintain a fork?
But if you need one, maybe this should be mentioned somewhere and/or
reflected in the package name?

Andreas
