build failure on mac

[Deb]

I am getting the following error while trying to build ns3 on mac. Any help is appreciated!

$ ./waf build

Waf: Entering directory `xxx/yyy/build'

Hi,

don't blame MacOs: it is not responsible for your programming mistakes.

There's no class "UtilizationTracker" in ns-3. As a consequence, it must be your (and without its code, we can't do anything - almost).

In any case, PointToPointNetDevice does not have any member function named GetDataRate.

Summarizing... double error. Re-check your code and don't assume that a function is there just because its name sounds right.

Use the code documentation and read the module sources instead.
