Like many things in life this pain seems to be somewhat self
inflicted, I suppose. More into.

After emerging gcc-3.4.6 I had troubles with the gcc-config stuff so I
removed gcc-3.3.6. However it appears that removing 3.3.6 removed
libstdc++ also. I updated slocate's database and saw that the only
libraries with that name are gone now:

dragonfly ~ # slocate libstdc++.so.5
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/libstdc++.so.5.0.7
/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/libstdc++.so.5
dragonfly ~ # updatedb
dragonfly ~ # slocate libstdc++.so.5
dragonfly ~ #


More info:

dragonfly ~ # gcc-config -l
 [1] i686-pc-linux-gnu-3.4.6 *
 [2] i686-pc-linux-gnu-3.4.6-hardened
 [3] i686-pc-linux-gnu-3.4.6-hardenednopie
 [4] i686-pc-linux-gnu-3.4.6-hardenednopiessp
 [5] i686-pc-linux-gnu-3.4.6-hardenednossp
dragonfly ~ # gcc-config -B
/usr/i686-pc-linux-gnu/gcc-bin/3.4.6
dragonfly ~ # gcc-config -B -L
/usr/i686-pc-linux-gnu/gcc-bin/3.4.6
dragonfly ~ # gcc-config -L
/usr/lib/gcc/i686-pc-linux-gnu/3.4.6
dragonfly ~ # gcc-config -X
/usr/lib/gcc/i686-pc-linux-gnu/3.4.6/include/g++-v3
dragonfly ~ # gcc-config -E

It seems that my AMD64 machine has a number of these:
mark@lightning ~ $ slocate libstdc++.so.5
/mnt/gentoo32/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/libstdc++.so.5.0.7
/mnt/gentoo32/usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/libstdc++.so.5
/mnt/gentoo32/usr/lib/libstdc++-v3/libstdc++.so.5.0.6
/mnt/gentoo32/usr/lib/libstdc++-v3/libstdc++.so.5
/usr/lib64/libstdc++-v3/libstdc++.so.5.0.6
