The problem comes when Apache, via APR-UTIL I think, has BDB symbols
that come from an incompatible BDB. In your case you are using GDBM
which doesn't provide BDB symbols.

Debian plays a few other tricks as well, run nm on a Debian BDB 4
library and you will see symbols like __db_open_4000, a plain tarball
BDB 4 gives symbols like __db_open. I think this means that Debian's
BDB 3 and BDB 4 can coexist. Do other distributions do this?

If configure finds APR-UTIL using a BDB that is different from the
Subversion requirement it should at least produce a warning. An error
that requires some overriding command line switch might be better.
