i don't see why you need an outside module to do binary conversions.
they are one of the most simplest things to do really and take literally less than 10 lines for each conversion to create the function.

Code

output:

5
101
1100001 1100010 1100100 1110101 1100011 1110100
abduct

Code

def bin2dec( number )
result = 0
number.split(//).each do |digit|
result = (digit.to_i + result) * 2
end
return result/2
end

def dec2bin( number )
number = number.to_i;
return 0 if( number == 0 )
result = '';

while( number != 0 )
result = (number % 2).to_s + result;
number = number / 2;
end
return result;
end

puts bin2dec '101'
puts dec2bin 5

mystring = "abduct"
binaryarray = []
chararray = []

mystring.each_char do |char|
binaryarray.push dec2bin char.ord
end

puts binaryarray.join ' '

binaryarray.each do |binary|
chararray.push (bin2dec binary.to_s).chr
end

puts chararray.join ''
