That sounds like a libtool bug.  (We don't put the -lc in there 
ourselves.)  You might want to report this to the libtool developers.

If this is a version of libpcap prior to 0.9.1, get the source to 0.9.3 
from tcpdump.org, apply the attached patch to it, build and install it, 
and, if necessary, reconfigure Ethereal to build with that version and 
try it.  (The patch is as yet untested.)
