Subject: undefined method `map'

Hi,

A biostar user helped me with a code to help me download fasta files
from KEGG. The code is named get_fasta4

-----CODE START HERE--------
#!/usr/bin/env ruby
require "rubygems"
require "bio"

serv = Bio::KEGG::API.new

# search for xac + hypothetical
xac = serv.bfind("T00084 hypothetical")
# get the IDS into an array
ids = xac.map { |gene| $1 if gene =~/^(.*?)\s+/ }
# retrieve fasta and print
ids.each { |id| puts serv.bget("-f -n 1 #{id}") }
-----CODE END HERE--------

However, in my system, Debian Testing, I got an error:

marcelo@marcelo:~$ get_fasta4
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': iconv
will be deprecated in the future, use String#encode instead.
/home/marcelo/bin/scripts/get_fasta4:10:in `<main>': undefined method
`map' for #<String:0x87a9f38> (NoMethodError)
marcelo@marcelo:~$
marcelo@marcelo:~$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [i486-linux]
marcelo@marcelo:~$ 
marcelo@marcelo:~$ gem search soap

*** LOCAL GEMS ***

soap4r (1.5.8)
soap4r-ruby1.9 (2.0.5)
soap4r-ruby19 (1.5.9)
marcelo@marcelo:~$ 

Could you help me?

Thank you very much!
