build failed of package

I am trying to install the rpvm package doing this:

C:\R\rw2000\bin>rcmd install rpvm_0.6-2.tar.gz

'.' is not recognized as an internal or external
command,
operable program or batch file.

make: *** /rpvm: No such file or directory.  Stop.
make: *** [pkg-rpvm] Error 2
*** Installation of rpvm failed ***

Removing 'C:/R/rw2000/library/rpvm'

What does this error message tell me?
