[PyMOL] pymol install

[yp s. <sun...@ya...>]

Dear pymol users,
 
I try to install pymol in Linux system as following
 
(1) download pymol-v1.5.0.1.tar.bz2 and decompress it to /opt directory.
(2) go into /opt/pymol/setup directiry and enter the command "setup.sh"
 
Then I see the install success information:
 
============================================
Creating "./pymol" startup script with 
PYMOL_PATH=/opt/pymol/setup
============================================
If you need to move PyMOL in the future,
re-run "./setup.sh" afterwards.
============================================
You may now want to copy or link:
"/opt/pymol/setup/pymol"
to something like "/usr/local/bin/pymol"
============================================
Enjoy!
 
However, when I type "pymol" command, I get the error information:
 
./pymol: line 14: /opt/pymol/setup/ext/bin/python: No such file or directory
./pymol: line 14: exec: /opt/pymol/setup/ext/bin/python: cannot execute: No such file or directory
 
Could you tell me why?
 
Thanks!
