OK, I managed to verify that this doesn't fail to compile on
2.1.0~beta2/amd64.

No idea either, hrm. Are you sure that all other architectures share
this problem? The CMake output is opaque enough that it could be other
issues.
I can try to upload a new mpqc3 package which dumps some more CMake
files on failure, maybe.

Actually, between beta2 and final, the struct GaussianGmEvalScratch got
removed entirely:
https://github.com/evaleev/libint/commit/397043b4926fb66d3efa5c58092dc5c02480bfce
I asked in a comment about the mpqc compile test.
Maybe there is some C++ magic which makes it appear again, but if I
ugprade libint2-2/libint2-dev to current unstable I get:
|$ g++ -I/usr/include/eigen3 -I/usr/include/libint2 /tmp/test.cxx -o
