To make the crust: In a food processor, pulse the flours, sugar, baking powder, and salt until combined. Add the butter and pulse the mixture until it resembles cornmeal mixed with pea-sized bits of butter, about 10 times. Add the egg white, vinegar, and water, and pulse 1 or 2 times; don't let the dough form into a ball in the machine. (If the dough is very dry add a couple of teaspoons of cold water.) Remove the bowl from the machine, remove the blade, and bring the dough together by hand. Form the dough into a disk, wrap it in plastic wrap, and refrigerate at least 1 hour.

Lightly spray a 9-inch pie pan with oil. On a lightly floured surface, roll the dough into a thin disk, about 13 inches in diameter. Transfer the dough to the prepared pie pan and trim the edges, leaving about one inch hanging over the edge. Tuck the overhanging dough underneath itself to form an edge even with the rim. Flute the edge as desired. Freeze the crust for 30 minutes.

Preheat the oven to 400 degrees F. Line the crust with foil and fill with pie weights. Bake on the center rack until firm and just cooked, about 20 minutes. Reduce the oven temperature to 350 degrees F. Lift the foil to remove the beans, return to the oven, and bake until golden, about 10 minutes.

Meanwhile, make the filling. In a large bowl, whisk the pumpkin, evaporated milk, brown sugar, eggs, orange zest, and rum. In a small bowl, combine the cornstarch, cinnamon, ginger, nutmeg, and salt. Sift the dry ingredients over the pumpkin mixture and whisk until thoroughly blended.

Pour the filling into the prepared crust and bake until the filling is just set but not cracked, about 1 hour. Cool on a rack, serve warm or at room temperature.
