configure: error: Report this to tcpdump-workers@lists.tcpdump.org, and include the
config.log file in your report.  If you have downloaded libpcap from
tcpdump.org, and built it yourself, please also include the config.log
file from the libpcap source directory, the Makefile from the libpcap
source directory, and the output of the make process for libpcap, as
this could be a problem with the libpcap that was built, and we will
not be able to determine why this is happening, and thus will not be
able to fix it, without that information, as we have not been able to
reproduce this problem ourselves.
