Could you please verify that dansguardian really gets linked against
libuClibc++.so.0?

When I did exactly as you said (only symblinking
i386-gentoo-linux-uclibc-c++ -> g++-uc) dansguardian still got compiled
with gcc's g++ and it was linked against libstdc++.so.6. When I also had
a g++ -> g++-uc it really used g++-uc from uclibc++, but then the
compile failed.

I have also tried the ~x86 2.9.3.0_alpha version with similar results.
(time missing)

(I just discovered there is a dansguardian 2.9.3.1 out so I will have to
submit a bug report for an updated ebuild)
