More info: I tried revdep-rebuild and it gave dozens of lines for .la files:

 broken /usr/kde/3.5/lib/kde3/cupsdconf.la (requires
/usr/lib/gcc/i386-pc-linux-gnu/3.4.6/libstdc++.la)
  broken /usr/kde/3.5/lib/kde3/dcopserver.la (requires
/usr/lib/gcc/i386-pc-linux-gnu/3.4.6/libstdc++.la)
  broken /usr/kde/3.5/lib/kde3/kabc_dir.la (requires
/usr/lib/gcc/i386-pc-linux-gnu/3.4.6/libstdc++.la)
.....
All prepared. Starting rebuild...
emerge --oneshot --pretend =app-text/aspell-0.50.5-r4
=sys-devel/gettext-0.15 =sys-libs/db-4.2.52_p4-r2
=app-text/hunspell-1.1.4-r1 =app-text/poppler-0.5.3
=dev-libs/libsigc++-2.0.16 =dev-libs/gmp-4.2.1 =dev-cpp/glibmm-2.8.4
=dev-cpp/gtkmm-2.8.3 =dev-libs/libpcre-6.6 =dev-libs/libusb-0.1.12
=media-libs/tiff-3.8.2-r2 =kde-base/arts-3.5.2-r1
=kde-base/kdelibs-3.5.2-r6 =media-libs/smpeg-0.4.4-r8
=media-libs/taglib-1.4 =media-sound/amarok-1.4.3-r1
=media-sound/beast-0.6.4

but it dies at the first emerge with:
checking for C++ compiler default output file name... configure: error:
C++ compiler cannot create executables.
