Ok, I got hg built in my home directory on the server and am ready to
bisect. Except, I can't find a point in the history of the default
branch where

$ cat ../test.cc
#include "eigen/Eigen/Eigen"

using namespace Eigen;

int main() {
  return 0;
}

compiles to set as the --good commit. Does anyone know of one? If I go
back to commit 2071, I appear to only get a couple of errors, but it
is a similar template-related problem.

$ CC ../test.cc
"../eigen/Eigen/src/Core/MathFunctions.h", line 92: Error: Could not
find a match for Eigen::ei_random<Eigen::T>().
"../eigen/Eigen/src/Core/MathFunctions.h", line 93: Error: Could not
find a match for Eigen::ei_random<Eigen::T>(int, int) needed in
Eigen::ei_random<Eigen::T>().
Error: Cannot continue processing because of prior errors.
Compilation aborted.
