No, I did not remember to run 'gcc-config -f 1' because I never knew that it should be done and no portage message advised me to do so. `man gcc' or `man gcc-config' also report that there is no manual on these packets. Gentoo's Upgrading GCC wiki also says nothing about this command... > What's the output of 'gcc-config -l'? # gcc-config -l * gcc-config: Active gcc profile is invalid! [1] x86_64-pc-linux-gnu-4.8.3 Nice! Ok, trying # gcc-config -f 1 * Switching native-compiler to x86_64-pc-linux-gnu-4.8.3 ... >>> Regenerating /etc/ld.so.cache... >>> >>> [ ok ] * If you intend to use the gcc from the new profile in an already * running shell, please remember to do: * . /etc/profile What exactly shall I remember to do? Ok, # gcc-config -l [1] x86_64-pc-linux-gnu-4.8.3 * Now # emerge --update --deep --with-bdeps=y --newuse --backtrack=90 --ask world emerges all three above packages. Trying to emerge pdftk. Done. Ok. Thank you. But why there was no hint about it after updating gcc? Well, there was a reference to Gentoo's Upgrading GCC wiki but nothing more...
