Roger was jsut asking about libnl-dev and ts-xen-build-prep on IRC. I
suspect he may be investigating...

Roger pointed at 
http://logs.test-lab.xenproject.org/osstest/logs/58974/build-amd64/5.ts-xen-build.log

Which has:
        Checking for LIBNL3... no
        configure: WARNING: Disabling support for Remus network buffering.
            Please install libnl3 libraries, command line tools and devel
            headers - version 3.2.8 or higher
        
But Wheezy has libnl-dev 1.1-7, which I think it might just be too old.
It also has libnl-3-dev which is 3.2.7 in Wheezy, i.e. still not quite
new enough.

Jessie has 3.2.24 which will be more than sufficient.

I think the upshot is that it is pointless installing libnl-dev on
Wheezy, at least for current Xen maybe older branches worked with older
libnl, I didn't check...

Ian.
