First off, don't use 'make install' except when building a distro
package, as you'll end up with multiple versions of libguestfs
installed and that causes pain.

In Fedora, we do 'make install DESTDIR=...' in a buildroot, and then
remove the 'perllocal.pod' file before building the final distro
package.  See:

http://pkgs.fedoraproject.org/cgit/libguestfs.git/tree/libguestfs.spec?id=93def76b1d5b6efd4da7ed7d3ceadbb817b5c959#n911

So if you're building a distro package, then you probably want to do
something similar to this and the problem doesn't arise.

When we install the Perl files, all we do is run Perl's
ExtUtils::MakeMaker.  See:

https://github.com/libguestfs/libguestfs/blob/master/perl/Makefile.am
https://github.com/libguestfs/libguestfs/blob/master/perl/Makefile.PL.in

So if there is a proper solution to this, it must lie with ExtUtils.

Rich.
