lvm-common is the Debian package that switches between LVM versions on the
same system. If you install the "lvm10" or "lvm2" packages then this will get
installed by default.

The Debian LVM binaries get installded lib /lib/lvm-<version> and lvm-common
decides at run-tim which one is the most appropriate to use.
 
Of course you must use the Debian packages to get this, if you build your own
tools from source then you're on your own :) (building your own kernels is fine
though)
