 That's really not the point here. We all know the dangers of things like
 untested destroot runs with elevated privileges and as a matter of
 principle it should never be allowed to become a habit just to prepend
 `sudo` to every command.

 Esp. not in a development context.

 "Base" acknowledges this through `macportsuser` and by dropping privileges
 for the stages that don't require them, and really the actual configure
 step itself should be included in that as it may have unexpected side-
 effects (the actions that may require root privileges are or can all be
 handled before the actual configure command is run). That's a different
 issue, but addressing it would make the issue at hand independent of
 whether or not `sudo` is used.

 But really, why would errors in `fs-traverse` NOT be ignored in the two
 functions at hand (and why would they check anything other than
 `worksrcpath`, `configure.dir` and `build.dir` as far as those locations
 are distinct)?
