Turns out that the wxCommandEvent::Clone() linking error is due to a bug
in GCC4.9 (#752733) (as Andreas already knows from another bug).

I uploaded wxwidgets3.0 3.0.1-2 a short while ago with a workaround for
this GCC 4.9 bug, so versioning your wx BD(s) >= 3.0.1-2~ should do the
trick (if you backport to wheezy, you can drop the versioning as the
3.0.1-1 backport is unaffected since wheezy doesn't have GCC 4.9 as the
default compiler).

I've attached a patch of where I got to above, plus the versioned BD.
This patch is against your SVN repo.

The new wx upload hasn't yet appeared on the mirror I use yet, so I've
not test built this, but given it got to the linking stage before
hitting the GCC4.9 issue, I'm pretty confident this should at least get
you a build.

Cheers,
