Just do what I do in these situations: create a symbolic link, called
"libc.so.4" pointed to whatever libc.so you have.  For example, in my
/lib directory I have libc.so.4.7.6 and libc.so.5.3.12.  The .5 is in
ELF format, while the .4 is for the older a.out format.  Even if you
didn't know this, try one first (the highest numbered), then the other.

Example (as root):

# cd /lib
# ln -s libc.so.5.3.12 libc.so.4

I suspect the above would not work in your case as I suspect the program
in question is looking for the a.out format library.  The above command
would work, but your program would bomb; so, instead:

# cd /lib
# ln -s libc.so.4.7.6 libc.so.4

Then try your program again.  I have Slackware '96 (3.1) and I already
have a symbolic link called libc.so.4 and it points to libc.so.4.7.6

Best of luck, feel free to get back to me if more assistance is required
