That's already been explained by Stata to you, but cryptically. The
-version- statements are only part of the story; they don't in
themselves _guarantee_ that the program will work with in this case
10.1. They only _guarantee_ that it won't work with versions less than
10.1!

In this case what bites is that the Mata code was compiled with a
later version.

-version- is a stranger and more limited command than might be
guessed. There is much more discussion at

I have a certain version of Stata and have come across a user-written
program that is apparently written for a later version of Stata. What
are my options?

If you're confused by this, you're in good company. There is a lot to
explain. A mantra that may help is that -version- is not a time
machine; so it does not set everything to what it was in 10.1, in this
case.
