Hi Harufumi,
Did you have any problem when compiling/linking on your FreeBSD system?
Did you check that $ROOTSYS/lib/libTreeViewer.so exists?
if yes, can you do the following:
root > gSystem->Load("libTreeViewer");
root > .class TTreeViewer
If all the above works, can you try:
root > gSystem->Load("libTreeViewer");
root > TFile *f = new TFile("tree1.root");
root > TTree *t = (TTree*)f->Get("t1");
root > t->StartViewer();
