wxWidgets-3.0: update to 3.0.3.1

[mojca (Mojca Miklavec)]

This ticket is about update of wxWidgets-3.0 to version 3.0.3.1.

It's slightly unlikely that wxPython 3.0.3 would be relased, at least not in the very near future. But maybe the old python additions works on top of wxWidgets 3.0.3?

I tried updating the port, but there are a number of issues:

• clang 425 segfaults when compiling, we should carefully check the behaviour on Slow Leopard and across some other platform verion
• if we blacklist the compiler just for wxWidgets, p5-wx segfaults in the same way, probably all other dependencies as well
• according to perl developers one should not mix the compilers and recompile perl (but I see no realist way to do that)
• perl packages fail quite a number of tests

I'll post patches once I'm slightly further with the experiments.
