[Libvir] Problem to compile virt-manager in debian etch

Hello all, I have a problem to compile the virt-manager in a Debian etch (64 bit version). I got the virt-manager source from mercurial repository. Bellow the output autogen.sh command: ./autogen.sh libtoolize: `config.guess' exists: use `--force' to overwrite libtoolize: `config.sub' exists: use `--force' to overwrite libtoolize: `ltmain.sh' exists: use `--force' to overwrite configure.ac:7: required file `./config.rpath' not found man/Makefile.am:6: `%'-style pattern rules are a GNU make extension pixmaps/Makefile.am:3: wildcard $(srcdir: non-POSIX variable name pixmaps/Makefile.am:3: (probably a GNU make extension) src/Makefile.am:15: wildcard $(srcdir: non-POSIX variable name src/Makefile.am:15: (probably a GNU make extension) src/Makefile.am:35: `%'-style pattern rules are a GNU make extension src/Makefile.am:38: `%'-style pattern rules are a GNU make extension src/Makefile.am:41: `%'-style pattern rules are a GNU make extension src/Makefile.am:44: `%'-style pattern rules are a GNU make extension src/Makefile.am:26: variable `schema_SOURCES' is defined but no program or src/Makefile.am:26: library has `schema' as canonic name (possible typo) src/Makefile.am:11: variable `libexec_SOURCES' is defined but no program or src/Makefile.am:11: library has `libexec' as canonic name (possible typo) src/Makefile.am:4: variable `bin_SOURCES' is defined but no program or src/Makefile.am:4: library has `bin' as canonic name (possible typo) src/Makefile.am:18: variable `desktop_SOURCES' is defined but no program or src/Makefile.am:18: library has `desktop' as canonic name (possible typo) src/Makefile.am:8: variable `python_SOURCES' is defined but no program or src/Makefile.am:8: library has `python' as canonic name (possible typo) src/Makefile.am:22: variable `dbus_SOURCES' is defined but no program or src/Makefile.am:22: library has `dbus' as canonic name (possible typo) src/graphWidgets/Makefile.am:5: `:='-style assignments are not portable src/graphWidgets/Makefile.am:5: shell pkg-config --variable=codegendir pygtk-2.0: non-POSIX variable name src/graphWidgets/Makefile.am:5: (probably a GNU make extension) src/graphWidgets/Makefile.am:6: `:='-style assignments are not portable src/graphWidgets/Makefile.am:6: shell pkg-config --variable=defsdir pygtk-2.0: non-POSIX variable name src/graphWidgets/Makefile.am:6: (probably a GNU make extension) src/virtManager/Makefile.am:3: wildcard $(srcdir: non-POSIX variable name src/virtManager/Makefile.am:3: (probably a GNU make extension) src/virtManager/Makefile.am:7: python_DATA:$(srcdir: non-POSIX variable name src/virtManager/Makefile.am:15: `%'-style pattern rules are a GNU make extension Any idea? regards. -- Marco Sinhoreli
