problems installing comedi on redhat

hi all,
i'm having some problems compiling and installing comedi-0.7.68, on
redhat9.0 kernel 2.4.21-15.EL.
below is a typical error during compile (there are many similar such
messages).  also below is the errors i get from make install.
any ideas how to fix this?
thanks,
jon
