How are you reading the raster data?

10.4's GCC 4 is missing the supc++ library as well as cc_dynamic.
The fix is to use g++ and drop those libraries, as Apple will not
be providing them anymore ("working as advertised" is the resolution
for the Radar bug I opened on this...)

This is reflected in the CUPS 1.2 sources as well as Apple's CUPS
1.1.x Darwin sources.

You have to use the backend - there are no character devices for USB
printers on OSX.
