Sounds like you need to set LD_LIBRARY_PATH so that ld finds the
libstdc++ shared library file. This isn't a libstdc++ problem, it's how ld
works.

It exists, but ld doesn't know how to find it.

for bourne shell:
LD_LIBRARY_PATH=/path/to/shared/libs/; export LD_LIBRARY_PATH

for C shell (eurgh):
setenv LD_LIBRARY_PATH /path/to/shared/libs/

N.B the value of LD_LIBRARY_PATH should be the directory containing the
shared lib, not the path to the lib itself.

Hope that helps,
