This isn't a problem compiling it, but running it.

	export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/wxPython/lib

before running "make".

Or add /usr/lib/wxPython/lib to /etc/ld.so.conf then run ldconfig (as
root).

-L switches only tell the linker where to look for libraries. The
loader uses $LD_LIBRARY_PATH and ld.so.cache (generated by ldconfig).

Or you can manually hack the definition of WXWIDGETSLIB in
Platform.make to include -Wl,-rpath,/usr/lib/wxPython/lib. This will
embed the path into the executable.
