A PPA for Lucid is still on my todo list. Will probably happen after
the 4.2 release which will be soon.

All those perl libraries are available in Ubuntu, too. Just do:

$ sudo apt-get install libtext-template-perl libconfig-inifiles-perl

Looks fine until here.

Each of these errors looks to me as if "make install" is run a third
or at least a second time.

It's ok to ignore these errors. But it is a bug that it isn't checked
if something.d already links to a directory and subsequent calls to
"ln -s something.d somethingelse.d" do make symbolic links into
somethingelse.d if it already exists.

We will fix that. Thanks for the report!

		Kind regards, Axel
