That "something" is exactly the problem.   Only some versions of
wxWidgets need this, and only for some configurations.   The
wx-config tool is supposed to tell us what libraries are needed so
we can link them.  But it doesn't mention X11.    So how are we to know?

I'll go further and say it is a wxgtk bug that this should be visible
to the calling program at all.  The calling program doesn't use or
need to know about libX11.   If wxgtk wants to call into it, fine, 
but why expose this to the calling program?

FWIW wxgtk 2.8 still works and doesn't have this problem.
It is only versions >= 2.9 that are broken.
