+tcpdump explicitly checks for a static version of libpcap in
+../libpcap-[0-9]*.[0-9]*(.[0-9]*)?([ab][0-9]*)? relative to its build dir
+if found, tcpdump is linked statically against this lib
+
+The patch removes the check for the static lib and headers in this relative
+location for tcpdump's configure script.
