Build ns3 failed but build on Debian success

[YunQiang Su]

Binary package hint: doxygen

I upload the ns3 package, and it's successfully build on Debian Unstable.

But when sync to Ubuntu, it failed to build.

Maybe it is caused by Ubuntu delta.
And I successful built it on doxygen 1.7.3-1 before, so I guess it's not caused by 1.7.3 diff with 1.7.4
