I still get the false packet loss:

The same happens when scanning scanme.nmap.org

Also, not quite sure why, but make check (for zenmap?) apparently fails here:

make[1]: Leaving directory `/tmp/nmap-libpcap-1.7/nsock/src'
Traceback (most recent call last):
  File "run_tests.py", line 15, in <module>
    start_dir=glob.glob("build/lib.*")[0],
IndexError: list index out of range
make: *** [zenmap_check] Error 1


I don't have any build/ directory after building nmap
