Hmm - after double checking: everything is indeed caused exactly by
gmsh being unable to find LAPACK library.  Namely, there seems to be a
bug in FindBLAS CMake module, so that CMake is unable to properly
detect LAPACK, when built against ATLAS libraries (strange that the
bug is reported almost a year ago, and it's still sitting there - I
guess I'll have to try to report it at CMake mailing list again).
When I fixed it, and re-compiled gmsh, it is meshing both tutorial
files, and my geometry, properly.  Thus - apologies for the fuss, but
still I'd suggest to change gmsh CMakeList.txt file, so that it error
out in case LAPACK not found.
