The wiki says that you need libqt3-mt-mysql
for ubuntu, but I think that that page is referring to the pre-qt4 state.

These are some lines from my dependencies script *for Fedora* (works for 
  8, 9 and 10)

  echo "          ********************************* "
   echo ""
  echo "         Update to qt4: does NOT install the 15 Meg of qt4-docs"
  echo "         Note that these file names are case sensitive"
  echo ""
  yum -y install qt qt-devel qt-MySQL qt4 qt4-devel qt4-mysql qt4-x11
  echo "  Add the libmysqlclient libraries to LDPATH through ld.so.conf"
  echo "/usr/lib/mysql" >> /etc/ld.so.conf
  ldconfig
  echo ""
  echo "          Otherwise you get the error: QSqlDatabase: QMYSQL3 
driver not loaded"
  echo "          when myth tries to contact the database, as the client 
library is not found."

You will have to troll through the ubuntu repos to find the exact names 
which Ubuntu uses for these particular files. And I think this listing 
misses some of the things like QtWebkit, where the actual name has 
changed with every different version in Fedora so that the error spit 
out by myth's configure does not directly name the package. Hope you 
have better luck.
