The libdb* linkage seems to come from the output of 'apu-1-config 
--libs'. It returns '-ldb' and so the APR.so part of mod_perl is 
linked with libdb*.

However, I see no reason for anything that uses libaprutil1 to be 
linked with libdb. As far as I see, the DB part of aprutil is in 
another, private, library, apr_dbm_db.so, which is already linked with 
libdb. I think apr-1-config --libs should not include DB libraries.

The following patch would help. It goes a bit further by removing any 
ldap libraries from the output too (not that there are any now):

--- a/apu-config.in
+++ b/apu-config.in
@@ -122,7 +122,7 @@ while test $# -gt 0; do
     DBM_LIBS=""

-    flags="$flags $LDAP_LIBS $DBM_LIBS $LIBS"
+    flags="$flags $LIBS"
     ;;
     --ldap-libs)
     flags="$flags $LDAP_LIBS"


In the mean time, I think we can patch mod_perl to call apu-1-config 
with --avoid-dbm as a workaround.
