Hi, on completion of any allinone installation, you're ask to set a bunch of PATHs:
----- IMPORTANT NOTICES: [...] (2) You MUST put /opt/ns2/ns-allinone-2.29/tcl8.4.11/library into your TCL_LIBRARY environmental variable. Otherwise ns/nam will complain during startup. (3) [OPTIONAL] To save disk space, you can now delete directories tcl8.4.11 and tk8.4.11. They are now installed under /opt/ns2/ns-allinone-2.29/{bin,include,lib} ----- Isn't step 2 unnecessary? I forgot to do so and all worked fine for me. Also, in optional step 3 you're free to delete the folder you've set a path to before anyway... -Matt
