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:

======
Configured wxWidgets 3.0.2 for `x86_64-dt-linux-gnu'

Which GUI toolkit should wxWidgets use? GTK+ 2 with support
for GTK+ printing libnotify
Should wxWidgets be compiled into single library? no
Should wxWidgets be linked as a shared library? yes
Should wxWidgets support Unicode? yes (using wchar_t)
What level of wxWidgets compatibility should be enabled?
wxWidgets 2.6 no
wxWidgets 2.8 yes
Which libraries should wxWidgets use?
STL no
jpeg sys
png sys
regex builtin
tiff sys
zlib sys
expat sys
libmspack no
sdl no
=======

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?
