Inefficiency of SAS Programming

R depends on all of those things to run, but you only have to use those programs through R. The software depends on these other tools, but the human doesn't have to switch interfaces.
In fact, it doesn't even depend on them to run. Most Windows users don't have perl, latex, any of the unix tools, an external tcl/tk system (R includes one), or a C compiler. (Most *nix users have them, but don't need them for running R, with the exception of tcl/tk, which is used by a number of packages.) You only need them to build packages, or to build R.

A system that requires Excel for its success is not a complete system.
To be fair R depends on perl (although this dependence seems to be decreasing lately and possibly will be eliminated), latex and a bunch of unix tools. Developing GUIs depends on tcl/tk or other external system and developing fast code can require that some of it be written in C.
