So, only in 7.

I have (64bit)
rpm -qa | grep cairo
lib64cairomm1.0_1-1.8.0-1mdv2009.1
lib64cairo2-1.8.6-3mdv2009.1
python-cairo-1.8.2-1mdv2009.1
lib64cairo-devel-1.8.6-3mdv2009.1
libcairo2-1.8.6-3mdv2009.1

Actually, I compiled with cairo support:

grep cairo grass70/conf_grass70_64bit_pentium.sh
  --with-cairo \

grep cairo grass70/include/Make/*
grass70/include/Make/Grass.make:CAIRODRIVER_LIBNAME   = grass_cairodriver
grass70/include/Make/Platform.make:#cairo
grass70/include/Make/Platform.make:CAIROINC                  =
-I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/freetype2
-I/usr/include/libpng12
grass70/include/Make/Platform.make:CAIROLIB                  = -lcairo
-lfreetype -lfontconfig
grass70/include/Make/Platform.make.in:#cairo
