No such file or directory

[wwshen@engin.umich.edu]

   I install the arlad and it begins to work. But
after I reedited the file in arlad and then typed "make" and
"make install" in the directory arla, I got the following
error. Let me show what I typed to run arlad:

iceaxe# /usr/arla/bin/mount_xfs /dev/xfs0 /arla
iceaxe# /usr/arla/bin/arlad

   Then I typed the following:

iceaxe# kauth wwshen at ENGIN.UMICH.EDU
wwshen at ENGIN.UMICH.EDU's Password:

   Could you tell me why I got the message "No such file or directory"?
In fact I can not enter the subdirectory engin.umich.edu. Thanks a
lot for your answer in advance.
