Well there's #nlst method (using openbsd site as an example):

require 'net/ftp'
names = nil
Net::FTP.open('ftp.openbsd.org','anonymous','blah') do |ftp|
  ftp.chdir('/pub/OpenBSD/4.1')
  names = ftp.nlst('*')
end
p names

That will give you the names of directories _and_ files _and_ links in
the 4.1 directory.

If you want just the directories in a directory, you can do this:

require 'net/ftp'
dirs = []
Net::FTP.open('ftp.openbsd.org', 'anonymous', 'blah') do |ftp|
  ftp.chdir('/pub/OpenBSD/4.1')
  dirs = ftp.ls('*').select { |item| item[0,1]=~/^[l|d]/ }
end
dirs.map! { |item| item.split.last }
p dirs

That will give you just the directory and link names in the 4.1
directory (but not if they have spaces in the name).

Does that make sense at all?
