[ns] ns-allinone installation problem

["Enrique Lavalle Pareja" <elaval@essex.ac.uk>]

Hi all,

I have installed "ns-allinone-2.1b7a" in a Linux (Red Hat 6.2) machine, and
ran the ./validate with no problems. But when tried to run ns I get the next
message:

****************************************************************************
*******************
esenet7-elaval-26-% ns
application-specific initialization failed: Can't find a usable init.tcl in
the following directories:
    /root/usr/tmp/ns-allinone-2.1b7a/lib/tcl8.3
/root/usr/tmp/ns-allinone-2.1b7a/lib/tcl8.3 /root/usr/tmp/lib/tcl8.3
/root/usr/tmp/lib/tcl8.3/library /root/usr/tmp/library
/root/usr/tmp/tcl8.3/library /root/usr/tcl8.3/library
/root/usr/tmp/ns-allinone-2.1b7a/lib/tcl8.3



This probably means that Tcl wasn't installed properly.

% exit

But the init.tcl does exits! Could someone help me out?

Regards,
Enrique
