The aquilles heel of package managers isn´t consistency, but lack of packages.
I appreciate the benefit of distro-agnostic package management, but unless you rely on a portable toolchain, or distribute statically linked binaries exclusively, we fall short from the panacea of portability (many other options available, yes, but packages are needed!)
I have personally leveraged pkgin[1] for consistency. I can simply drop pkgsrc[2] in my home directory and use the same tools in *bsds, smartos, linux, macos and cheese.
