As I understand the license terms and your intentions it does not, the language seems very clear you may use it with or without modification and you may redistribute it subject to certain conditions. You plan to use it with modification - the license appears to make no restrictions on how you use it. However I am not a lawyer and not competent to give legal advice. If it really matters you should get a legal opinion - it is ONLY my layman's opinion that failing to do so will not land you in trouble. -- Steve O'Hara-Smith
