Question visualizer problem in ns3

i downloaded the tarball pygraphviz-1.1 and moved into the ns3 directory and den untarred it..
after that i made changes in the wscipt(src/mesh/examples/wscript) and added the module 'visualizer' to it..
and ran the command..

./waf --run "src/mesh/examples/mesh --x-size=2 --y-size=2 --step=100 --start=0 --time=1 --packet-interval=1 --packet-size=1024 --interfaces=1 --pcap=1" --vis
i have set the parameters such that only 1 packet is transferred and then the output is as such

Waf: Entering directory `/home/cpu56/ns-allinone-3.11/ns-3.11/build'
Waf: Leaving directory `/home/cpu56/ns-allinone-3.11/ns-3.11/build'
'build' finished successfully (2.465s)

Modules built:
aodv applications bridge

emu energy flow-monitor

assert failed. cond="uid != 0", msg="Assert in TypeId::LookupByName: ns3::VisualSimulatorImpl not found", file=../src/core/model/, line=443
Command ['/home/cpu56/ns-allinone-3.11/ns-3.11/build/debug/src/mesh/examples/mesh', '--x-size=2', '--y-size=2', '--step=100', '--start=0', '--time=1', '--packet-interval=1', '--packet-size=1024', '--interfaces=1', '--pcap=1', '--SimulatorImplementationType=ns3::VisualSimulatorImpl'] terminated with signal SIGSEGV. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

what is happening?
