It works fine on my system. What is the output of ldd?

It's not the performance. If you use single quote, you are
asserting that you are using literal string. I believe this
improves the readability of code because there will be less
places you have to pay attention to. I know this is just a
stylistic issue and don't care much about other one's script
but I write that way for my own code.

Thanks. I'll commit it shortly.
