Yes, we do, but

$ ls -l /usr/lib/gcc/hppa-linux-gnu/4.0.3/libstdc++.so
lrwxr-xr-x 1 root root 23 Apr  6 02:08 /usr/lib/gcc/hppa-linux-gnu/4.0.3/libstdc++.so -> ../../../libstdc++.so.6

we can only have one libstdc++.so.6 installed. that's currently the
library from 4.1. So maybe we need to bump the soversion of libstdc++
on hppa?
