It might be just my system (probably) but digikam-0.7.4 fails to compile with gc-3.3.6 but compiles with 3.4.4. I have both of the compilers installed side by side, and I switch them with gcc-config.

Sorry, but switching arbitrarily between incompatible gcc versions is a bad idea. This is bound to fail if dependencies have been already compiled w/ the other version. Don't do this.
