Firefox build errors on PowerPC

[Felix Friedlander]

When trying to build www/firefox (37.0.2) on my PowerPC box (PowerBook G4), I consistently hit this error:

In file included from /usr/ports/www/firefox/work/mozilla-release/obj-powerpc-portbld-freebsd10.1/gfx/layers/Unified_cpp_gfx_layers2.cpp:2:0:
/usr/ports/www/firefox/work/mozilla-release/gfx/layers/basic/BasicCompositor.cpp:20:56: fatal error: skia/SkCanvas.h: No such file or directory
 #include "skia/SkCanvas.h"              // for SkCanvas
                                                        ^
compilation terminated.

This happened each of the 3 times I attempted to build it. It occurs with both the system GCC and with GCC 4.8.4 from ports. Is there anything I can do to fix this error?
