A workaround is to make a symbolic link to libstdc++.so.6 with the

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.
