Need help getting back to v2.4.11

[Bertus]

A while ago I installed qBittorrent by following the instructions on the download page. So I executed:

sudo add-apt-repository ppa:hydr0g3n/ppa and,
sudo apt-get update && sudo apt-get install qbittorrent

Today I suddenly got v2.5.0rc4 through the auto-update (I wasn't aware of this). This version is blacklisted at most trackers I use, so want to go back to the latest stable. How can I do this? I tried installing the tar.gz but I get errors when a do ./configure:

/usr/bin/moc-qt4 -DHAVE_MODULES -DQT_NO_DEBUG -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4 -I. conf4.cpp -o conf4.moc
g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DHAVE_MODULES -DQT_NO_DEBUG -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4 -I. -o conf4.o conf4.cpp
In file included from conf4.cpp:703:
libboost.qcm:8: fatal error: boost/version.hpp: No such file or directory
compilation terminated.
make: *** [conf4.o] Error 1

... and I have no clue what this means.


Also, how can I prevent getting beta's in the future?

nevermind, I removed it and installed an old version with the Software Center. Too bad it's a bit outdated (v.2.4.3) but I guess I just have to be patient and wait for an update...
