Thanks for clearing that up for me so quickly. Works perfectly with [declare -stdlib zexy] but I'll try [declare -stdlib zexy -stdpath zexy] too.

best, Rick

You can either add a [declare -stdlib zexy] to the patch in question,

Actually, in the case of zexy you need:

[declare -stdlib zexy -stdpath zexy]

because zexy comes with an external library _and_ abstractions. You can test with [dirac~] (external) and [cart2sph] (abstraction).
