iproute2-2.6.18.20061002-as-needed.patch

This removes the two library refrences from LDFLAGS and puts them in GENLLIBS,
which appears after libdl's usage, so the library gets linked in.  Not sure if
that's the best place for it, but it should fix the compilation problems...

no, GENLLIB has a different meaning ... you dont want to be utilizing that var

fixed in cvs, cheers
