I think that this is more related to the way you use your compiler than
anything related to ns. It seems that you are using old g++ libraries
(from gcc 2.7.1) which are clashing with (what I guess are) newer
libraries. I would guess that this functionality has been moved from the
old libstdc++.a to libgcc.a in newer versions.

My guess would be that the library files libstdc++.a and libgcc.a are
linked by default. The compiler uses the search path specified in
LIBRARY_PATH to determine how to find these files. I would suspect that
yours is configured as such that the libstdc++.a file is found in
/usr/local/lib before the one that should be found (I'd guess that this
should be in 
/sw/packages/cygnus/progressive-98r1-v0/H-sparc-sun-solaris2.6/bin/../lib/gcc-lib/sparc-sun-solaris2.6/2.9-cisco-98r1)
So you could set the environment variable LIBRARY_PATH to
/sw/packages/cygnus/progressive-98r1-v0/H-sparc-sun-solaris2.6/bin/../lib/gcc-lib/sparc-sun-solaris2.6/2.9-cisco-98r1):/usr/local/lib
and this might work, but if you're using a newer version of gcc/g++ than
2.7.1, I think it's probably bad to have the library for 2.7.1 in
/usr/local/lib.

I would guess that this problem manifests itself whenever you try to
compile anything in c++, and it's really one for your tech support people
rather than ns-users.

My 0.02p (worth much more than $0.02 :-).
