Hi, in w3c-libwww there is an utility libwww-config which can dump some config information about when you built libwww package, I found a problem that 'libwww-config --libs' does not print name libwwwzip, so programs using libwww sometime miss symbol from libwww.zip.so because they do not link into program, and startup fails.
fixed in Red Hat 7.x
