If you want to concatenate all those list items with spaces and include that expanded value in a string, as you're doing here, you'll need to use the expand operator ({*}). Technically, build.cmd and build.target (and all other MacPorts options) are lists too, though they might only contain one item at the moment. To properly expand all those lists into strings, you'd use: "{*}${build.cmd} {*}${build.args} {*}${build.target}".

Perhaps I was. Ok, never mind then, I was just taking a wild stab at something that might be wrong, given that the custom build phase seemed unnecessary and therefore wrong, and since we weren't told in what way it "didn't work".
