kdb2_dbopen() should be defined in the lidbdb compiled by krb5.
Perhaps you're not looking there.

Which ChangeLog are you seeing this in?  I'm not finding it.

No.  This is wrong.  What is already in util/db2/include/db.h is
correct.  k5db2_dbopen() is an internal interface in libkdb5.

I'm not sure what exactly you're doing wrong.  What is the exact error
you're getting?  What OS, compiler, etc.?  Is it happening at compile
time or at runtime?  Is it happening with programs in the krb5 tree,
or with other programs compiled against krb5?

The "grand scheme" is mostly... rename dbopen() to kdb2_dbopen() in
db.h to avoid conflicts with any installed libdb.  Unconditionally
build libdb as a static library.  Require any programs using krb5's
libdb to link against the static libdb from the krb5 tree.

Note that this will change in krb5-1.3; the object files from the
in-tree libdb will be pulled into libkdb5 to avoid the problem of a
shared library having to depend on symbols in a static library.
