error for runstructure_vasp

Dear Dr. van de Walle,
First of all, thank you so much for sharing this nice codes for free. I am a new user of the code. When I run runstructure_vasp for a test as instructed in the manual, there come several mistakes. I attach the prompts here. Would you please give some advice to address this problem? Thank you very much.

Actually, the POTCAR.Z exists in the corresponding directory

/home/izha0001/fj78/vasp/potential/potpaw_PW91/Cu
[izha0001@monarch Cu]$ ls
DDE.Z POTCAR.Z PSCTR.Z V_RHFIN.Z V_TABIN.Z

The garbled line:
/Cu/POTCAR.Z: No such file or directoryl/potpaw_PW91
makes me think there is a nonprintable character accidientally inserted in your .ezvasp.rc
Try:
cat -v ~/.ezvasp.rc
to see it. And then delete it with a text editor (you may have to retype the line if your editor does not show nonprintable characters).

Thank you so much
