Log Message:
-----------
* The variants did not do the right thing as they didn't 
  hinder us installing ikiwiki into a system with two 
  or more incompatible perl versions. And since MP has
  still not gathered version-specific dependencies, we're
  building this on our own here and require that 
  PREFIX/bin/perl has at least some version we can work
  with (5.10 as of now). At the same time we hint the user
  at the problems he might run into if he just upgrades
  his Perl version from an older version.
  (closes #26320)
* Bump ikiwiki's version to 3.20100926
