how to update to 1.2

[Schade Frank (sf)]

I'm running SquidGuard: 1.1.4, Berkeley DB 2.7.7 with squid-2.4.STABLE1-6 on a redhat 7.2 box. What I've have to do for upgrading to SG 1.2 (especially how to move from Berkeley DB 2.7.7 to 3.x.) Please give also common known details for I'm not familiar with "make". Thanks Frank
