Eigen3 related build failure in compute_k.cc

Many thanks for 9c3df01f50be9300f0ddd45dedc4b5faf31d7bd6, but I see a build failure in compute_k.cc now:

The eigen3 package is at 3.3.1, is that too old/too new?

@evaleev many thanks for the fix, it built fine now: https://buildd.debian.org/status/fetch.php?pkg=mpqc3&arch=amd64&ver=0.0~git20170114-2&stamp=1484906348&raw=0

For the record, when I built it on my personal notebook, I got an ICE in twobody_intermediates_ta.cc:

Maybe that was due to not enough RAM or such, as it builds fine on the Debian autobuilder.
