Maybe something is wrong with the package pin. Try to use
Pin: version 4.1.1-11*
instead. If this does not work then you should post the output of
apt-cache policy libstdc++6
so that we can see how your apt rates the different versions of the

If your system is in a consistent state then it should be possible to
put the library on hold without breaking other packages. This hold will
of course block upgrades of all dependent packages. This can become
awkward pretty soon since libstdc++6 is an important library.

I think the following should work: Run "aptitude keep-all" to cancel all
scheduled actions. Start aptitude in interactive mode; there should be
no broken packages. (Check with 'b'; if there are broken packages you
have to fix them first.) Put libstdc++6 on hold. If you now use 'U' to
request an upgrade then aptitude should detect the problems with the new
versions of the packages that depend on libstdc++6. It should propose
different ways of resolving the conflicts; one of them should be
'suggests 50+x keeps'. If you accept that resolution then aptitude
should be able to upgrade all packages which are not affected by
libstdc++6. (Use ',' and '.' to view the different proposals and '!' to
accept the best one.)
