Those commands are meant to be run at the console.  I normally use a 
Cygwin console, but the commands are designed to work fine in the 
Windows CMD console too.

They should also work from within R, if you run them within the system() 
function, and have your system set up properly.  For example:

 > setwd("d:/svn/MyR")
 > system("R CMD build rgl")
* checking for file 'rgl/DESCRIPTION' ... OK
* preparing 'rgl':
* checking DESCRIPTION meta-information ... OK
* cleaning src
make: Nothing to be done for `clean'.
* removing junk files
* checking for LF line-endings in source and make files
* checking for empty or unneeded directories
WARNING: directory 'rgl/src/ext/GLsdk/GL/codegen' is empty
* building 'rgl_0.85.tar.gz'

(With the usual settings in Rgui, this will be buffered and will appear 
all at once:  you can uncheck the menu item "Misc | Buffered output" to 
have the lines show up reassuringly one at a time.)

The most likely reason for this not to work is that your system path is 
not set correctly.  The relevant path is the one shown by 
Sys.getenv("PATH") while running R.  Mine currently shows

 > Sys.getenv("PATH")
 
 
 
 
         PATH
"c:\\Rtools\\bin;c:\\Rtools\\perl\\bin;c:\\Rtools\\minGW\\bin;f:\\cygwin\\usr\\local\\bin;f:\\cygwin\\bin;f:\\cygwin\\bin;f:\\cygwin\\usr\\X11R6\\bin;c:\\util\\misc;c:\\windows\\system32;f:\\R\\svn\\r-devel\\R\\bin;f:\\texmf\\miktex\\bin;c:\\progra~1\\htmlhe~1;f:\\program 
files\\subversion\\bin"

(If you read it closely, you'll notice some duplication.  It's hard to 
keep a Windows path clean.)
