As alberta uses the same symbols for all dimensions, we can only use
alberta with a predefined dimension. Thus you need to add the
dimension dependend flags aswell. You should do this by defining
ALBERTA_DIM=?? (simly at the top of your Makefile.am) or by defining
WORLDDIM=??. Both will make ALBERTA_CPPFLAGS (and LIBS) contain the
correct dimension specific part.
