Installing flent on OS/X with homebrew
`pip install flent matplotlib`
`brew install fping`
Netperf in homebrew is installed without demo mode by default, so we need to edit the recipe slightly, also demo mode fails to build under OS/X, requiring a tiny patch to netlib.c ( http://www.netperf.org/pipermail/netperf-talk/2013-December/001162.html ). The following recipe changes the URL to a prepatched version that I host and changes the configure line to enable demo mode.
`brew edit netperf`
```
class Netperf < Formula
desc "Benchmarks performance of many different types of networking"
homepage "http://netperf.org"
url "http://fakkelbrigade.eu/i/netperf-2.7.0.tar.bz2"
sha256 "a9c2fe4c3bc572912fd320c39f819d4d494675d743132e6094e2663982464fb6"
def install
system "./configure", "--disable-dependency-tracking",
"--enable-demo",
"--prefix=#{prefix}"
system "make", "install"
end
test do
system "#{bin}/netperf -h | cat"
end
end
```
`brew install --build-from-source netperf`
Run flent:
`flent rrul -p all_scaled -l 60 -H your-server -t your-run -o your-run.png`

Thanks. I've combined the patch and config item in to a Homebrew recipe here: dgchurchill/homebrew-core@53f5a1d

I used this last night as well - also had to brew install pyqt to get flent-gui working

However, it works great.

Is there any chance of this being merged into mainline Homebrew? (As in, the netperf --demo-mode option)?

Thanks for this gist. I wasted around 4 hours cursing my inability to understand the autoconf, make, ecosystem while trying to make it work without realizing that a patch to the original source was required for this to run.
