You can just install it normally.  You may also want to recompile any apps
based on it, but this is not strictly necessary.  Although different
versions of libprotobuf.so are not binary-compatible (C++ sadly makes
compatibility too difficult to achieve), we use libtool's version numbering
to make sure that binary-incompatible versions of libprotobuf do not
overwrite each other.  So, any binaries you compiled against the old version
will continue to use the old version at runtime.
If you want to uninstall the old version, then run "make uninstall" from the
same directory where you you ran "make install" to install it.

BTW, 2.2.0 will be out in the next week or two.
