Hi all,

I am having trouble getting package xps to work, and would really
appreciate any help I can get.

I have succesfully installed root_v5.34.01 on my ubuntu 12.04 OS
as described on in the xps package readme file I added ROOTSYS to PATH
and LD_LIBRARY_PATH by entering these lines in the terminal:
export ROOTSYS=~/ROOT/root  (I make a folder ROOT in which I unpacked root.)
              export PATH=$ROOTSYS/bin:$PATH
              export LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH

 I also added above 2 lines in .bashrc

root seems to run fine.

next, I download xps_1.16.0.tar.gz and run:
sudo R CMD INSTALL xps_1.16.0.tar.gz

I get the following error message:

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

So apparently ROOTSYS variables are not set right? I tried anything I
could think of but I am lacking in understanding here.

Thanks alot!
