problem with build on Solaris

I'm trying compile (gcc/g++ 3.4.3) pgadminIII 1.6 beta3 on Solaris
Nevada with wx1.7.1 and I received following error:

./base/factory.cpp: In member function `int pgaFactory::addIcon(char**)':
./base/factory.cpp:120: error: invalid use of undefined type `struct
wxImageList'
/tmp/hlipa/wx17/include/wx-2.7/wx/generic/listctrl.h:16: error: forward
declaration of `struct wxImageList'
./base/factory.cpp: In static member function `static void

/tmp/hlipa/wx17/include/wx-2.7/wx/generic/listctrl.h:16: error: forward

gmake[2]: *** [factory.o] Error 1

Any idea what is wrong? Is it problem with wx1.7.1?

Thanks Zdenek
