Check if wget is installed in the system.

[boschmitt]

When you try to run the script without wget being installed it keeps going util patch application reports an error. Should be easy to check it the system contains 'wget'.

glucose.sh: line 3: wget: command not found
tar: Error opening archive: Failed to open 'glucose-syrup-4.1.tgz'
can't find file to patch at input line 3
Perhaps you used the wrong -p or --strip option?
