Great :-)

Some screenshots would be nice as well, btw. ;-)

Sorry, I forgot to mention that you need libltdl as well. libtool is the
command line program used at build time while that lib is used by
collectd. In Ubuntu, the required package should be libltdl-dev.

Hrm, that should still work … anyway, I don't currently have time to see
why that could fail.

Right.

The "5.10" directory is a symlink to the latest Perl version, i.e.
5.10.1 in your case.

HTH,
