Build errors while attempting to build Mozilla Sunbird

[John Mahowald]

I'm attempting to build Sunbird, Mozilla's standalone calendar.

With the Firefox package's mozconfig and patches, I got the build to
start (FC4, i386), but it failed with this error:

nsFontMetricsPS.h:344: error: 'FTC_Image_Desc' does not name a type
nsFontMetricsPS.h:347: error: 'FTC_Image_Cache' does not name a type
nsFontMetricsPS.h:481: error: 'FTC_Image_Desc' does not name a type
gmake[5]: *** [nsDeviceContextPS.o] Error 1

Full rpmbuild log is here:

Any hints as to what component or patches I could start with would be
appreciated.
