WX Widgets Version

I have WX Widgets 3.0.2, which includes WX Widgets 2.8 compatibility.

My PGAdmin3 compilation (configuration) fails with:

configure: error: The version of wxWidgets required (2.8) is not supported by 
the installations in /usr.

My WX Widgets configuration is:

So that you can see that wxWidgets 2.8 IS supported (as a compatibility mode).

Is it the case that PGAdmin3 SHOULD compile and work with the latest WX 
Widgets, provided that 2.8 compatibility is enabled?

If so, is there a problem with the configuration that fails to detect this 
support?
