[ns] INSTALLATION PROBLEM?

[Lateef O Ogunleye <loo697@mail.usask.ca>]

During installation i got this:

warning: Route to base_stn not known: dropping pkt

During the validation process i got this:
Starting Simulation...
Test output agrees with reference output
All test output agrees with reference output.
validate overall report: some tests failed:
     ./test-all-webcache
to re-run a specific test, cd tcl/test; ../../ns test-all-TEST-NAME
Notice that some tests in webcache will fail on freebsd when -O is
turned on.
This is due to some event reordering, which will disappear when -g is
turned on.

Can anyone explain to me what the impact of this will be on running the
simulation to address some Mobile IP problem issues?The version
installed is ns-allinone-2.1b8a/ns-2.1b8a


Thanks
