loading shared lib symbol in ddd

Hi,
In 6.2, I cannot load the shared lib symbols anymore.

I do like that:

#> ln -s /my_home/…/so.g/mylib_g.so /my_home/tmp/mylib_g.so
#> ln -s /my_home/…/so.g/mylib_g.so /my_home/tmp/mylib_g.so.2.0
#> export LD_LIBRARY_PATH=/my_home/tmp:$LD_LIBRARY_PATH
#> pdebug 8000&

ddd is set to get env from pdebug

when I execute the exe in ddd, I get several error message like:
Error while mapping shared library sections:
mylib_g.so.2.0: No such file or directory
Error while mapping shared library symbols:
mylib_g.so.2.0: No such file or directory

Why ddd doesn’t find that file??

thanks,
Alain.
