Hi,

(I bet this has come up before, but I was unable to dig up the answer  
in the archives or Google.)

When I run "install.sh" of ns-allinone-2.28 on MacOS X 10.4  
("Tiger"), the final link of ns fails:

...
/usr/bin/ld: warning multiple definitions of symbol _abort
common/tclAppInit.o definition of _abort in section (__TEXT,__text)
/usr/lib/gcc/powerpc-apple-darwin8/4.0.0/../../../libm.dylib 
(abort.So) definition of _abort
/usr/bin/ld: warning multiple definitions of symbol _random
tools/random.o definition of _random in section (__TEXT,__text)
/usr/lib/gcc/powerpc-apple-darwin8/4.0.0/../../../libm.dylib 
(random.So) definition of _random
/usr/bin/ld: Undefined symbols:

XCPQueue::GAMMA_
collect2: ld returned 1 exit status
make: *** [ns] Error 1
Ns make failed!
See http://www.isi.edu/nsnam/ns/ns-problems.html for problems

This may be due to the new gcc-4.0.0 in Tiger - is there a fix?

Thanks,
Lars
