[htdig] Can't find libstdc++ even though it's there

[<ian...@di...>]

On configure I'm getting the request to install libstdc++...

However:
rpm -q libstdc++ produces libstdc++-3.2.3-39

and a "locate libstdc++" gives me:

/usr/lib/libstdc++.so.5
/usr/lib/libstdc++.so.5.0.3
/usr/lib/libstdc++-libc6.2-2.so.3
/usr/lib/libstdc++.so.2.9
/usr/lib/libstdc++.so.2.8
/usr/lib/libstdc++-2-libc6.1-1-2.9.0.so
/usr/lib/libstdc++-3-libc6.2-2-2.10.0.so
/usr/lib/libstdc++.so.2.7.2.8
/usr/lib/libstdc++.so.2.8.0
/usr/lib/libstdc++.so.2.9.dummy
/usr/lib/libstdc++.so.2.7.2
/usr/lib/libstdc++-libc6.1-1.so.2

What do I need to do to point configure in the right direction? Thanks.
