Even though its dynamically linked the GPL still applies. The LGPL is designed to allow you to link to the software without requiring you to use the GPL license. Also since you have made your binary available you are required to make the source code you have used to make this release publicly available. I don't think anyone cares enough to sue you, however you are clearly in violation.
