What this looks like is a library versioning problem, maybe? On my
system, ber_sockbuf_io_udp is exported by /lib64/liblber-2.4.so.2.10.3,
and "ldd" on /lib64/libldap_r-2.4.so.2.10.3 shows that that library will
be pulled in automatically. Maybe it's not happening like that on your
box. It's a bit weird though because both those libraries are supplied by
the same openldap package, so it's hard to see how they could be out of
sync. Maybe you have another copy of one of those libraries floating
around, and the wrong copy is getting pulled into your link?
I'd suggest some investigation with "ldd" and "nm -D" to see what's what.
