Not quite LCD, but that's close to the truth. Basically, a binary
numpy package built against liblapack-dev will work with ATLAS when it
is installed. Is suspect that one built against libatlas-base-dev may
not work without ATLAS installed.
It's specific packaging for Debian-and-spawn, not a general numpy
requirement. Which is one reason why looking at a distribution's
build-deps is not very useful for inferring details about the
dependencies about the upstream packages.
