Some netcat implementations does not support unix domain sockets (-U).
Distros that ship these implementations often also ships socat, that
do support this.
This is a reworked patch based on the openSUSE libvirt package. The
original patch may be found in this source rpm:
http://download.opensuse.org/source/distribution/11.1/repo/oss/suse/src/l...
* configure.in: Check for --with-socat and set USE_SOCAT in config.h
* src/remote_internal.c: Honour USE_SOCAT by selecting between
netcat/nc and socat at compile time.
