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.

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.
