A workaround is to make a symbolic link to libstdc++.so.6 with the name of libstdc++.so in /usr/lib or /usr/local/lib or other dynamic library path like the following.

ln -s /usr/lib/libstdc++.so.6 /usr/lib/libstdc++.so

AFAICT, this is incorrect and should be something like ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/lib/libstdc++.so (where x86_64-linux-gnu depends on your platform). Normally this isn't a problem since to above-mentioned directory is in ld.so.conf, but that (apparently) isn't handled correctly by GHC. A less permanent workaround is to just add /usr/lib/x86_64-linux-gnu to your LD_LIBRARY_PATH in your environment before running anything GHC related.

This is an indication that you have not installed your distribution's -dev package for the library in question. You should do so instead of making the symlink manually.

Many distros have started to *not* install a /usr/lib/libstdc++.so symlink (nor even any /usr/lib/libstdc++*.so files at all) in /usr/lib, preferring to use the above-mentioned directory instead and listing it in /etc/ld.so.conf. It has something to do with getting saner multilib (and multiarch?) support.
