Yes, -T is for the temporary cache directory name. I use the version number in the cache directory name or else the same cache files will be used if you try to upgrade to a new version.

It sounds like there is a problem with the "@argfile" handling. Your command is "pp @pp_build_exe.args"? This should load the arguments from the file "pp_build_exe.args", but it may not be doing this for your version of pp because it sounds like it is trying to run your argfile as a Perl script. Maybe try entering all of the arguments on the command line instead of using "@pp_build_exe.args" to load them from file.
