That can be done, I'm confident.

Well, it passed make describe and thus broke INDEX. IGNORE is not
checked when running make describe, I believe.

But the problem is really this:
With a port allowing USE_WX=2.4+ and WX_COMPS=python, it should go for
2.4 or 2.6, instead of selecting 2.8 and then failing.

I'm not happy with it setting such port on IGNORE. Why it should fail,
when perfectly legit option is available? It should bail out with IGNORE
when you select USE_WX=2.8 and WX_COMPS=python, never else.

Please commit this fix.
