error building dnssd_clientlib.c

 error: could not determine date and time: No such file or directory
*** Error code 1

and the line is:

const char VersionString_SCCS_libdnssd[] = "@(#) libdns_sd " 
STRINGIFY(mDNSResponderVersion) " (" __DATE__ " " __TIME__ ")";

and I thought that __DATE__ and __TIME__ where gcc built-ins...

?!

Cheers,
