[ccache] assistance with upgrading from ccache 2.4.

Hi Alex,

dpkg will tell you which package of cache you installed with your OS 
software installation tool.  configure ; make ; make install is 
independent of that tool.  You can check which version is being picked 
up in your PATH like so...

$ ccache --version

You can see where ccache is in your path like so...

$ which ccache

What you'll need to do in uninstalled ccache with dpkg, then do make 
install again.  ccache --version should be the latest then.  Keep in 
mind that you can have bother versions installed.  One installed in 
/usr, the other installed in /usr/local.  make install typically puts 
things in /usr/local unless you give configure a --prefix=/usr.  You can 
set the PATH env var to pick up /usr/local/bin before /usr/bin.  This 
would also work (but dpkg will only report whatever version it 
installed).  Check ccache --version after doing this...

$ export PATH=/usr/local/bin:$PATH

Good luck.
