tcpdump install issues

[FreeBSD MailingLists]

I have recently installed FreeBSD 5.3 from CD onto a couple of
servers.  I updated the /usr/src and /usr/ports to  RELENG_5.  When I
try to install tcpdump from the ports, the make fails with the last
line being

Error: shared library "pcap.2" does not exist
*** Error code 1

I know I didn't have this problem when I installed 5.3 on a couple of
servers last month, so does anyone know what is causing this?

TIA,
