 /Volumes/RM1_Homes/dallured/port/mp/libexec/macports/lib/port1.0/port_autoconf.tcl
 for `variable install_group`? Maybe it has been recorded incorrectly

 I don't believe that's correct. Within quotation-mark-delimited strings,
 interpolation occurs. For example, escape sequences like `\r` are replaced
 with other values (e.g. a carriage return); we don't want that here. We
 want to save the value to the variable literally without any
 interpretation or replacement. To accomplish that, we need to be using
 curly-brace-delimited strings, e.g.:

 {{{
 variable install_group {PSD\rain}
 }}}
