mysql – ruby excel reader, spreadsheet gem

Questions:

i am trying to read an excel file in ruby and then take the data and insert it into a mysql database. I am using the spreadsheet::excel and mysql gems. for some reason i cannot seem to be able to use the spreadsheet gem to open the file for reading… this is my code

require 'rubygems'
require 'spreadsheet'
require 'mysql'

Spreadsheet.client_encoding = 'UTF-8'

book = Spreadsheet.open '/home/data/teams.xlsb'

b1 = book.worksheet('team1')

i get this weird error when i run the script

/usr/local/lib/ruby/gems/1.8/gems/ruby-ole-1.2.11.1/lib/ole/storage/base.rb:376:in `validate!': OLE2 signature is invalid (Ole::Storage::FormatError)
    from /usr/local/lib/ruby/gems/1.8/gems/ruby-ole-1.2.11.1/lib/ole/storage/base.rb:368:in `initialize'

    from sizes_importer2.rb:7

i read somewhere that this gem might not be able to support the .xlsb files. i do not know if this is true or not but if it is can someone tell me how to go around it, or if there is something else wrong? i am utterly lost and would appreciate any help with this error. thank you
