I have run into a problem building libwmf under Mac OS X 10.3.9 (gcc 3.3):

Notice the extra /usr/local/lib w/o a library.

The strange thing is that I had successfully built the library on a similar machine with same OS, without gtk 2.6.x installed. Thus I crippled the configure script (i.e. hid the pkg-config files for gdk*), and presto, no more problems...

Is there a more elegant way of disabling the gdk-pixbuf plug-in? configure --help is of no help here.
