  # Patch lib/libnids-1.21_patched/configure.gnu so that CFLAGS and/or
  # CXXFLAGS with multiple words doesn't cause an error -- e.g.:
  #
  # === configuring in lib/libnids-1.21_patched
  # (/private/tmp/homebrew-justniffer-0.5.11-yNmj/justniffer-0.5.11/lib/libnids-1.21_patched)
  # configure: running /bin/sh ./configure.gnu --disable-option-checking
  # '--prefix=/usr/local/Cellar/justniffer/0.5.11'  'CXX=/usr/bin/llvm-g++'
  # 'CXXFLAGS=-O3 -w -pipe -march=core2 -msse4' 'CC=/usr/bin/llvm-gcc'
  # 'CFLAGS=-O3 -w -pipe -march=core2 -msse4' --cache-file=/dev/null--srcdir=.
  # configure: error: unrecognized option: `-w'
  # Try `./configure --help' for more information
  # configure: error: ./configure.gnu failed for lib/libnids-1.21_patched
  #
  # I submitted this patch to the upstream author, Oreste Notelli, on
  # 2011-12-22, so this patch will probably not be necessary with future
  # justniffer versions after 0.5.11.

    Sample invocation to get you started:
      justniffer -i en1 -p "port 80"
