kdb2_dbopen missing symbol . . . sorta

Interesting.  This doesn't get installed though?

        * db/db.c (kdb2_dbopen): Rename to avoid colliding with NetBSD
        libc.
I was looking at that, but I guess I misunderstood.  (db2's changelog)

Ok, it's an in-house perl module and it's linked against:
-lkadm5clnt -lkrb524 -lkrb4 -ldes425 -lgssapi_krb5 -lkrb5 -lgssrpc -ldyn
-lk5crypto -lcom_err -lsocket -lresolv -lnsl

And a -L/usr/kerberos/lib and a -R/usr/kerberos/lib and this is under
Solaris 2.6, 7, 8, and 9.

(i may have to audit some of those libraries  I'm not convinced all of
those are necessary, but we'll see)

Anyway, what I get is:
fatal: relocation error: file /usr/kerberos/lib/libkdb5.so.3: symbol
kdb2_dbopen: referenced symbol not found

This only began after I upgraded us from 1.2.5 to 1.2.7.  I compile
Kerberos with:
--prefix=/usr/kerberos --with-krb4
--with-tcl=/afs/bp.ncsu.edu/contrib/tcl83 --enable-shared

Am I doing something obvious wrong?  My own stuff isn't using kdb2_dbopen
directly and:
ghidora 5.8 [4:44pm] <2> ...NCSUlib-2.00> nm /usr/kerberos/lib/* | grep kdb2_dbopen
                 U kdb2_dbopen
                 U kdb2_dbopen
                 U kdb2_dbopen
                 U kdb2_dbopen
                 U kdb2_dbopen
                 U kdb2_dbopen
                 U kdb2_dbopen
                 U kdb2_dbopen
ghidora 5.8 [4:45pm] <0> ...NCSUlib-2.00>

it doesn't appear to be defined anywhere.
