Thanks Christian,
I "solved" (root seem to work correctly) the problem including the path to libstdc++.so.3 in the LD_LIBRARY_PATH. I'm relatively sure that no enviroment variable points to the path /usr/local/lib/ so i can't imagine how root have found the existence of this library!

The library is only used in the ASImage libs (libASImageGui, libASImage and libASPluginGS)

Anyway:

bash-3.00$ ldd libASImage.so

        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0xb7edd000)
        libtiff.so.3 => /usr/lib/libtiff.so.3 (0xb7e91000)
        libpng12.so.0 => /usr/lib/libpng12.so.0 (0xb7e6e000)
        libXpm.so.4 => /usr/X11R6/lib/libXpm.so.4 (0xb7e5f000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0xb7d98000)
        libstdc++.so.3 => /usr/local/lib/libstdc++.so.3 (0xb7d36000) 
        libm.so.6 => /lib/tls/libm.so.6 (0xb7d12000)
        libgcc_s.so.1 => 

/scratch/maurizio/local_install/programs/gcc-4.0.3/lib/libgcc_s.so.1 (0xb7d07000)

        libc.so.6 => /lib/tls/libc.so.6 (0xb7bdd000)
        libz.so.1 => /usr/lib/libz.so.1 (0xb7bcd000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0xb7bbf000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7bba000)
        /lib/ld-linux.so.2 (0x002e1000)

Bye
Maurizio
