That's the distribution restriction I use on my own releases. You'll notice tat as long as no money changes hands you haven't violated my conditions.
Under a principal known as "Fair Use" you would not be vioating the agreement even if an amount of money did change hands...as long as the sum of money was only sufficient and intended to cover your expenses.
It's profit motive that makes the difference:
Try to make money off my work and you are in violation.
Try to recoup your costs of redistribution and it is OK.
The distribution of payware without a distribution license is always a violation.
