That succeeds because of a "chain reaction" : wxGTK (wxWidgets based on=20
gtk) links against gtk, and consequently against pango and cairo. But it=20
is not guaranteed that you'll be using the gtk port of wxWidgets. What=20
if in the future somebody tries to make it work with wxX11 (wxWidgets=20
based on the Xlib without gtk), wxOS/2 or wxMAC ? Then (in addition to=20
the little work needed in wxt_gui.cpp) we won't have the magic link=20
against cairo and pango, and the compilation would fail.
