mongo: error while loading shared libraries

I get this error when I try to run mongo, in ubuntu.

mongo: error while loading shared libraries: libboost_thread-gcc42-mt-1_34_1.so.1.34.1: cannot open shared object file: No such file or directory

I upgraded to Karmic yesterday. I have installed mongodb-stable from the repo mentioned here. I tried to apt-get libboost, but there is no such package as libboost_thread. I also posted on mongodb-user, but I need a quicker reply, and hence I am posting here. The boost libraries I have are version 1.3开发者_如何学C8. Ask if you need any other help.

Thanks a lot.

Try installing libboost-thread1.34.1
