I can't find any evidence of this at the moment, but I thought there were at least some thorns which would attempt to build anyway, even if you had set NO_BUILD. This would be the case if the thorn didn't know about the NO_BUILD option (external library handling is very nonuniform, with each library having to implement the same logic), but I thought it also happened for some thorns which did know about the option. I might be misremembering though.</div><div><br></div></div><div apple-content-edited="true">
