Install \"xps\" package


I have little knowledge about R and informatics in general. I am trying to download and install the "xps"
bioconductor package but I get this error:

xps configuration error:

   You must set the shell variable ROOTSYS to the
   directory where ROOT resides and re-run R CMD INSTALL
   e.g., (using Bourne shell syntax):

      export ROOTSYS=/opt/root
      export "PATH=$ROOTSYS/bin:$PATH" 
      R CMD INSTALL xps

   Please consult the README file for more information

I have read the README file and downloaded root and unzipped it. According to the README file the two
following steps are:

2. set ROOTSYS to the `root' directory:

            sh family:
              export ROOTSYS=<path>/root
            csh family
              setenv ROOTSYS <path>/root

   3. now type the build commands:

            all shells:
              ./configure --help    [optional, shows e.g. <arch> for supported architectures]
              ./configure [<arch>]  [e.g. <arch>= linux or macosx (32bit) or macosx64 (64bit)]
              make                  [or, make -j2 for dual CPU machines]

            Note: ./configure should automatically detect the architecture, if not use e.g.
              ./configure linux (32bit) ot linuxx8664gcc (64bit)

Now, the root directory is the directory downloads. In downloads I tiped "export ROOTSYS=root" (step two)
Then I tried typing "./configure [<arch>]" (step 3) but I get this answer:
bash: arch: No such file or directory

Does anybody know what's wrong and what I should do? I know little or nothing about linux so I don't really
understand what's being done at each step...
