Please see http://wiki.powerdns.com/projects/trac/changeset/471

It is probably easiest to delete the red line from mtasker.cc and replace it
by the green lines, and recompile.

alternatively, apply
http://wiki.powerdns.com/projects/trac/changeset/471?format=diff
following the instructions on
http://wiki.powerdns.com/projects/trac/wiki/HACKING

Or, if you are feeling lucky, try compiling from Subversion which has this
fix included - see the instructions in the HACKING page mentioned.

Good luck!
