as there is no debian-package for the perl bindings of clearsilver, you have to add it manually to the tree of the cbox-tree

1) download
- get it from: http://www.clearsilver.net/downloads
- unpack (tar xzf . ...)


2) configuration
./configure --disable-python --disable-ruby --disable-csharp --disable-apache --disable-java --disable-compression --enable-perl --enable-gettext --prefix=/tmp/clearsilver-perl


3) fix a problem in scripts/document.py
change the first line to "#!/usr/bin/env python"


4) build it
- make
- make install


5) cp to the cbox
cp -a /tmp/clearsilver-perl/local/lib/perl/5.8.7/. cryptobox.conf.d/usr/lib/perl5
rm cryptobox.conf.d/usr/lib/perl5/perllocal.pod

6) dependencies
add python-clearsilver to the box (dfsbuild.conf)
