Bug and solution building: lib/atc/SparseMatrix-inl.h:704:17: error: variable type 'Vector<INDEX>' is an abstract class

…/…/lib/atc/SparseMatrix-inl.h:704:17: error: variable type ‘Vector’ is an abstract class

Vector counts(nCols());

The solution is to replace line 704
Vector counts(nCols());
with
DenseVector counts(nCols());

to match function return value type.

When compiling lammps-12May13 on OS X (10.8) with gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)
$cd src
$make yes-all
$make no-user-cuda
$make mac
I got the error above.
