ccache is enabled through the configure script environment, for example:
DEBUG: Environment: CFLAGS='-pipe -O2' CPPFLAGS='-I/opt/local/include'  
CXXFLAGS='-pipe -O2' CPP='ccache /usr/bin/cpp-4.0' CXX='ccache /usr/ 
bin/g++-4.0' F90FLAGS='-pipe -O2' LDFLAGS='-L/opt/local/lib' FCFLAGS='- 
pipe -O2' OBJC='ccache /usr/bin/gcc-4.0' INSTALL='/usr/bin/install -c'  
OBJCFLAGS='-pipe -O2' FFLAGS='-pipe -O2'  
"MACOSX_DEPLOYMENT_TARGET"='10.5' CC='ccache /usr/bin/gcc-4.0'

Hope it helps,
