location of lvm binaries in Linux::LVM

[David Bremner <bremner@unb.ca>]

Dear Chad;

On Debian, we had to apply the patch below to get your module to find 
the lvm binaries, which for us are in /sbin.

I could see it being distro dependent where these binaries ended up;
perhaps the nicest thing would be to have a configure option for
Makefile.PL.

In any case I guess you want the error messages to match the test :-).
