apt-get fails with an undefined symbol

[Jose Luis Alarcon Sanchez]

Hi Folks.

I just did a dist-upgrade. Thuesday, may 7, 5:45pm at Spain.

After this, when i try use again apt-get, i get this error output:

# apt-get
apt-get: symbol lookup error: /usr/lib/libstdc++.so.6: undefined symbol: 
__pthread_recursive_mutexattr
#

So, now i can not update the system. Be careful if you still do not fall in 
this.

Do you see a solution for this problem?. Maybe download manually next version 
of libstdc++ package?.
dpkg utility looks works fine...

I hope be useful for the Group.

Regards.

Jose.
