Local builds act a bit differently because they contain a hidden
'RPATH' ELF entry:

  $ eu-readelf -d ./fish/.libs/lt-guestfish | grep RPATH
  RPATH             Library rpath: [/home/rjones/d/libguestfs/src/.libs:/usr/local/lib]

This RPATH entry overrides LD_LIBRARY_PATH:

  $ LD_LIBRARY_PATH=/usr/lib64 ./fish/.libs/lt-guestfish --version
  guestfish 1.17.40

For the builds that we provide in Fedora and RHEL, we strip out RPATH:

  $ eu-readelf -d /usr/bin/guestfish | grep RPATH
  $ /usr/bin/guestfish --version
  /usr/bin/guestfish 1.17.36fedora=17,release=2.fc17

Install the 'hivex-devel' and 'libvirt-devel' packages (from RHEL)
before ./configure && make.

You may be able to do 'yum-builddep libguestfs' to install all the
dependencies; or else read the libguestfs.spec file (BuildRequire lines).
