validate overall report:some tests failed

After many modifications, I managed to install ns2.30 on Fedora 6.0 , but some validation tests failed. I got the following message at the end of validation test:
validate overall report: some tests failed:
to run a specific test, cd tcl/test; ./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.

I have install ns2.30 in usr,i have installed many times,but i don't where is the error. If you know,can you tell me ? Thank you very much!

After many modifications

Why ? No modifications are required.
( Fedora 6 is an old dead OS. Not supposed to be used.)

The prerequisites for ns2 are : # yum install \
gcc-c++ compat-gcc-34-c++ automake autoconf libtool libX11-devel \
libXext-devel libXau-devel libXmu-devel xorg-x11-proto-devel

This is a test with ns-allinone-2.30 on the Fedora 6 based CentOS5 / SL6, 32bits :
./validate

Code:

validate overall report: some tests failed:

    ./test-all-tcpHighspeed ./test-all-red ./test-all-cbq

Nothing to do. That's the expected result.
( And an even poorer result will appear, when it's a 64bits OS.)

The gcc/g++ 3.4.6 compiler may do a slightly better result :
Start from scratch in a new directory, and :
export CC=gcc34 CXX=g++34 && ./install
