There is something odd about the way it is being built:

Notice where it installs the library:

Making install in src
make[1]: Entering directory `/home/teuf/jhbuild-boxes/sources/libvirt-0.9.8/src'
make  install-am
make[2]: Entering directory `/home/teuf/jhbuild-boxes/sources/libvirt-0.9.8/src'
make[3]: Entering directory `/home/teuf/jhbuild-boxes/sources/libvirt-0.9.8/src'
test -z "/home/teuf/jhbuild-boxes/opt/lib64" || /bin/mkdir -p "/home/teuf/jhbuild-boxes/opt/_jhbuild/root-libvirt/home/teuf/jhbuild-boxes/opt/lib64"
 /bin/sh ../libtool   --mode=install /home/teuf/.local/bin/install-check   libvirt.la libvirt-qemu.la '/home/teuf/jhbuild-boxes/opt/_jhbuild/root-libvirt/home/teuf/jhbuild-boxes/opt/lib64'


And now where virsh thinks the library should have been installed:

Making install in tools
make[1]: Entering directory `/home/teuf/jhbuild-boxes/sources/libvirt-0.9.8/tools'
make  install-am
make[2]: Entering directory `/home/teuf/jhbuild-boxes/sources/libvirt-0.9.8/tools'
make[3]: Entering directory `/home/teuf/jhbuild-boxes/sources/libvirt-0.9.8/tools'
test -z "/home/teuf/jhbuild-boxes/opt/bin" || /bin/mkdir -p "/home/teuf/jhbuild-boxes/opt/_jhbuild/root-libvirt/home/teuf/jhbuild-boxes/opt/bin"
  /bin/sh ../libtool   --mode=install /home/teuf/.local/bin/install-check virsh '/home/teuf/jhbuild-boxes/opt/_jhbuild/root-libvirt/home/teuf/jhbuild-boxes/opt/bin'
libtool: install: warning: `../src/libvirt.la' has not been installed in `/home/teuf/jhbuild-boxes/opt/lib64'
libtool: install: warning: `../src/libvirt-qemu.la' has not been installed in `/home/teuf/jhbuild-boxes/opt/lib64'
libtool: install: warning: `/home/teuf/jhbuild-boxes/sources/libvirt-0.9.8/src/libvirt.la' has not been installed in `/home/teuf/jhbuild-boxes/opt/lib64'
libtool: install: /home/teuf/.local/bin/install-check .libs/virsh /home/teuf/jhbuild-boxes/opt/_jhbuild/root-libvirt/home/teuf/jhbuild-boxes/opt/bin/virsh


Finally right at the end:


I: 41 files remaining from previous build
....
I: Deleted: '/home/teuf/jhbuild-boxes/opt/lib64/libvirt.so.0.9.7'
I: Deleted: '/home/teuf/jhbuild-boxes/opt/lib64/libvirt-qemu.so.0.9.7'


The combination of these 3 sets of messages, makes me think you have
confused libtool into linking to the old binary

What arguments are you passing to 'configure' and what if any variables
are you passing to 'make install' ?


I can't reproduce any problem myself if I do

   cd libvirt-0.9.7
   ./configure --prefix=/tmp/libvirt
   make
   make install
   cd ../libvirt-0.9.8
   ./configure --prefix=/tmp/libvirt
   make
   make install

Daniel
