Hello, Well as far as xgraph is concerned, go to the xgraph folder and try to install it manually. Then you will come to know about getline function error. Open the respective file and change that getline to any other name at all places (there are only two places).
For nam, try to exit from the nam first and then execute the script, if in the script you made a call to nam then it will automatically open else when script finished, type nam <namfile>.nam, try the wireless-flooding.tcl, good example.
