Let's eliminate the obvious:
emerge -C ccache
emerge -1 =mono-2.4.2.3

Hmm, your right. I disabled the ccache option in make.conf and it compiled well. Can you take a little more time to please explain to me what exactly happened?

ccache sometimes fails to work correctly. It's rare, but it happens. Especially likely to happen when recompiling a package that's had only very small patches applied to it relative to a previously compiled version, in my experience. Often it's non-reproducible (fluke?).
