running psipred problem

Dear friends

I have installed the I-TASSER on fedora 16 (64bit). When I want to run the program, I see the following message:

[root@localhost I-TASSERmod]# ./runI-TASSER.pl -libdir /root/Desktop/I-TASSER/ -seqname P32903 -datadir /root/Desktop/run -usrname root
Your setting is:
-libdir =/root/Desktop/I-TASSER/
-seqname =P32903
-datadir =/root/Desktop/run
-usrname =root
-runstyle =serial
-homoflag =real
-idcut =1
-ntemp =20
-nmodel =5
1. make seq.txt and rmsinp
2.1 run Psi-blast
2.2 run psipred
sh: /root/Desktop/I-TASSER//bin/psipred/bin/psipred: No such file or directory
sh: /root/Desktop/I-TASSER//bin/psipred/bin/psipass2: No such file or directory
cp: cannot stat `protein.ss2': No such file or directory
2.3 run solve
2.3 run solve
2.3 run solve

Could you please tell me how could I solve this problem?

Thanks in advance
