The version I downloaded from the site does (did?) depend on AVX instructions and would die on startup. There are other ('nightly builds') that fix this. One of the goals of the current team seems to be portability.

FWIIW J is moving in this direction as well; the last release version of it (807) needed a special build for older intel hardware (they subsequently made separate binaries for older hardware). AVX has been around since 2011/2012, so it doesn't seem like that big a deal.
Admittedly I myself have older hardware kicking around I see no real reason to upgrade, but AVX is such a big win on array processing you might as well make it a dependency for the kinds of use cases Shakti or J get used for in business.
