[Scribus] GC used as a type?

[Kevin Walzer]

More difficulties compiling Scribus 1.1.4 on OS X 10.3:

In file included from ../../scribus/pageitem.h:30,
                  from ../../scribus/page.h:29,
                  from ../../scribus/scribusview.h:33,
                  from ../../scribus/scribus.h:48,
                  from prefs.h:27,
                  from prefs.cpp:1:
../../scribus/scpainter.h:155: error: 'GC' is used as a type, but is not
    defined as a type.
make[3]: *** [prefs.lo] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Any advice?
