Mongosniff binds against libpcap but I can't find any references about this in documentation:

1. ldd /usr/bin/mongosniff
   linux-vdso.so.1 => (0x00007fff66bff000)
   libmongoclient.so => not found

   librt.so.1 => /lib/librt.so.1 (0x00007f418c21b000)

Don't know the best place to add this (wiki, docs, ...) - so I leave that up to you

Thanks
