Comment(by dweber@…):

 I'm concerned that we need to directly address the version of tar used.
 Can you try this solution on Tiger?

 I'm considering these lines for the post-destroot of the data variant:

 {{{
         # tar-1.14 uses --strip-path, tar-1.14.90+ uses --strip-components
         set tarArg "--strip-components"
         set tarVersion [lrange [split [exec tar --version]] 3 3]
         set tarMaj [lrange [split $tarVersion .] 0 0]
         set tarMin [lrange [split $tarVersion .] 1 1]
         set tarRev [lrange [split $tarVersion .] 2 2]
         if (expr $tarMaj == 1 && $tarMin == 14 && $tarRev < 90) {
                   set tarArg "--strip-path"
         }
         system "tar $tarArg 1 -C ${destroot}/${vtkDataPath} -zxvf
 ${distpath}/${vtkDataFile}"
 }}}
