I've got it working now by loading the gui dll with wxPluginManager and 
by adding the following in the gui dll:

#include <wx/html/htmlwin.h>

class wxGUIModule: public wxModule
{
public:
     wxGUIModule()
     {
     }

     virtual bool OnInit()
     {
       AddDependency(CLASSINFO(wxHtmlWinParser));
       return true;
     }

     virtual void OnExit()
     {
     }

private:
     DECLARE_DYNAMIC_CLASS(wxGUIModule)
};

IMPLEMENT_DYNAMIC_CLASS(wxGUIModule, wxModule)
