[Click] Error compiling my package in Click for kernel level

[Harkeerat Bedi]

OK. I will look into that. Just wanted to add that I have a b-tree
data-structure in my program. I also have a recursive function which I call
in my class's destructor to delete the b-tree from memory. However, I use
"new" and "delete" to perform allocations and de-allocations so I think
they work with heap.

I will try to look more in to it. Please let me know if you have any more
guesses. Thanks once again.
