I have istalled tracegraph on FC8 alongwith NS2.31 but
not able to see the output.when it typed ./trgraph in terminal i am
getting the error "error while loading the shared libraries:
libXp.so.6: cannot open shared object file: NO such file or directory"

please suggest me also about the files .tr and .tr.ip and also how to
set path for tracegraph in linux as i already have LD_LIBRARY_PATH
for ns2.31.
