Comment 1 for bug 801407

More easy workaround:

if you have libnl 123 installed:
sed -i 's/libnl-2.0/lib-bad-nl-2.0/g' configure
sed -i 's/libnl-1/lib-bad-nl-1/g' configure
this way ntrack will be built with libnl3 only and will not fail.

if you have libnl 12 installed:
sed -i 's/libnl-1/lib-bad-nl-1/g' configure
this way ntrack will be built with libnl2 only and will not fail.
