Did you mean /usr/bin/maxima?
I put that option there, i.e.,
elif [ "$MAXIMA_LISP" = "sbcl" ]; then
exec "sbcl" --dynamic-space-size 2560 ....

This works! I'm remembering that I already stepped to this rake somewhere
half-year ago. While the given option indeed helps to compile lapack, the
computations with large bigfloats matrices can be a problem still (the same
issue - not enough memory, heap exhausted, welome to ldb). Migrating to 64
bit solved my problems that time.

This woud be nice!
