environment settings

[Mark Brethen]

Another oddity I noticed in the log is

:info:build ld: warning: directory not found for option '-L/opt/local/var/macports/build/_Users_marbre_ports_math_taucs/taucs/work/taucs/lib/darwin16/'

That’s a valid path!

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}".
