OK, this change should fix that:

http://trac.survex.com/changeset/d7ee3286eb62f48f485748b6bbae40a546833637/git

I'd recommend using wxWidgets 3.0 if you can though, as wxWidgets 2.8 is
no longer maintained - the last release (2.8.12) was just under 4 years
ago now.

It looks like Fedora 21 has it:
