has anyone successfully installed dbdbd?  this program has just the right level of simplicity and
power for what i want to do (manage a small to medium-sized flat file database).

i have downloaded and unzipped it onto my single-user machine and when i try and install it using
"ruby install.rb" as root (as per the documentation included with the program) i get the following
error message :

install.rb:10: undefined method '+' for nil (Name Error)

line 10 in install.rb looks like this :
dest = Config::CONFIG["sitelibdir"] + File::SEPARATOR + source

am i missing a library i need in order to install this program?  or is it something else that is so
obvious that i'm not seeing it?

thanks

joe

ps. i am running ruby 1.6.2 on linux.
