This is it. All working machines have 2.2 lnx kernel and libc-2.1.3.so
nonworking one has 2.4 lnx kernel and libc-2.2.1.so.

I changed line 121 of syscall.c to use:
   mktemp(template);
instead of 
   mkstemp(template);

I got his linker warning, but rsync was linked OK and is working fine now.

syscall.o: In function `do_mktemp':
syscall.o(.text+0x32f): the use of `mktemp' is dangerous, better use `mkstemp'

Dave, thank You for Your help. You guys are really great.
