Hi there

I am setting up an old rails app I did last year on my development  
machine,  
but it will not migrate the new db

I froze rails at 1.1.6…but not the gems

when I do a rake db:migrate I get the log at the bottom…my database  
looks  
fine, with an empty schema ready to go with permissions set…

maybe I need the old version of digest/sha1 ??? this is where it breaks

def scramble41(password, message)  
return 0x00.chr if password.nil? or password.empty?  
buf = [0x14]  
s1 = Digest::SHA1.new(password).digest  
\<\<\<\<\<  
this is line 551…  
s2 = Digest::SHA1.new(s1).digest  
x = Digest::SHA1.new(message + s2).digest  
(0…s1.length - 1).each {|i| buf.push(s1[i] ^ x[i])}  
buf.pack(“C\*”)  
end
