Although the ultimate answer is to get rid of perl entirely, in the same vein as your discussion, perhaps R could simply provide standalone executables for each perl program currently used by R (using perlcc to produce them).

I believe there is a free alternative to Microsoft's Help Compiler too but I just googled for it and was unable to locate it.

By placing all these items (and the UNIXish tools) in the \R\rw...\bin directory and using the registry as in Rcmd.bat and Rgui.bat found in batchfiles:
