Thanks for your reply. Fortunately I somehow managed to debug the error. 
The sad part was there was no mention of the line in which error 
occured! All that was posted is "
>> Error Loading File slab.rb
>> undefined method `*' for nil:NilClass" 
I am using Ruby 1.8.6 on Windows 7 (64 bit)by the way...
