environment settings

[Mark Brethen]

I used placeholders in the makefile then passed the environment variables using reinplace statements. That worked, however I’m getting a make: lib/darwin16/libtaucs.a: Permission denied. Sounds like I need to change the permissions after extracting the source. Is there a tar flag for that?

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}".
