A problem of using pyfort

[g950101 at gmail.com]

Hi,
I faced some problems during using pyfort. The log for installing
pyfort is attached:

running install
running build
running build_py
running build_scripts
copying pyfort -> build/scripts-2.4
changing mode of build/scripts-2.4/pyfort from 644 to 755
running install_lib
running install_scripts
copying build/scripts-2.4/pyfort -> /usr/bin
changing mode of /usr/bin/pyfort to 755
Pyfort Version 8.5.3

It seems to be no errors. However, It cannot
work perfectly while applying on the demo. The message is shown as:

I didn't find any solutions via internet. So I really
need your help. The OS on my computer is Fedora Core 5. Thanks in
advance.
