Those pesky oil leaks are what led to oil pump being trashed, and ultimately no oil P, and lockup. Sorry to hear, but oil leaks are not always 'normal', and need to be addressed immediately for severity, and what may be going on inside that only show telltales outside.

Not sure what kind of leakage Rhino might be experiencing. While the weeps that have been so commonly witnessed from head gaskets or cylinder seals are certainly a mess, definitely a matter of concern and absolutely an issue in and of themselves they are not causing dramatic nor traumatic losses in internal oil pressure nor volume and leading to pump failures.
So long as someone hasn't let that weep leak so long that you've lost volume they aren't running the engine to starvation. So it's not a likely concern to put the oil weeps that have been so prevalent against a pump failure. Even a head gasket that was so fouled up as to somehow hinder return from the top to the bottom would very likely have the engine make itself known in other ways before you shelled an oil pump.
The oil pumps we've heard about were either literally unable to be removed normally because of runout, actually trashed because of runout, or in Dave's case supposedly damaged by debris. Barring a significant leak through a pressurized internal oil galley, however, the leaks that have been witnessed so regularly so far, while a total pain in the ass, are separate issues from an oil pump failure.
Pesky they may be. But please don't be too concerned that you caused your engine to lock up and potentially do yourself real harm just because you continued riding it for a bit with the common leaks going on.
