This one is easy to explain: The command

grep #include /usr/include/arpa/inet.h

gives on 10.4:

#include <stdint.h>		/* uint32_t uint16_t */
#include <machine/endian.h>	/* htonl() and family if !_POSIX_C_SOURCE */
#include <sys/_endian.h>	/* htonl() and family if _POSIX_C_SOURCE */
#include <netinet/in.h>		/* in_addr */
#include <sys/param.h>
#include <sys/cdefs.h>

and on 10.5:

#include <_types.h>
#include <stdint.h>		/* uint32_t uint16_t */
#include <machine/endian.h>	/* htonl() and family if (!_POSIX_C_SOURCE 
|| _DARWIN_C_SOURCE) */
#include <sys/_endian.h>	/* htonl() and family if (_POSIX_C_SOURCE && 
!_DARWIN_C_SOURCE) */
#include <netinet/in.h>		/* in_addr */

This kind of incompatibility between 10.4 and 10.5 is unfortunately 
rather widespread, and packages depending on indirectly included header 
files often fail.
