[Inkscape-devel] Build error in latest BZR

Rendering test suite failed to compile Inkscape just a while ago, with this message:

make[2]: *** No rule to make target `libnr/nr_mmx_R8G8B8A8_P_R8G8B8A8_P_R8G8B8A8_N_TRANSFORM.S', needed by `libnr/nr_mmx_R8G8B8A8_P_R8G8B8A8_P_R8G8B8A8_N_TRANSFORM.o'. Stop. make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2

This build is on x86 Linux, using the normal build procedure. Probably there's a modification with Makefile.am file left unmodified.
