Thank you for comments. I applied `ruby-124-v6-19990413a.diff.gz' and 
`ruby-125-v6-19990414.diff.gz' to `ruby-1.2.4.tar.gz' and 
`ruby-1.2.5.tar.gz' respectively. Unfortunately I got same errors:

% ruby -r socket -ve 'p TCPsocket.open("www", "daytime").read'
ruby 1.2.4(99/04/09) [i386-freebsd2.2.6]
