This points toward a difference in resolver libraries. Especially since
you're using a statically linked client, the resolver used in the client
probably differs from the one your system uses.
Off hand, you might need an /etc/nsswitch.conf file. If you don't have
one, try 'echo hosts: files dns > /etc/nsswitch.conf'. That might work,
but if it doesn't then we can get serious....
Linux has a program called strace which will show all the system calls
a program makes. This includes all open() and stat() calls, even ones
made by libraries. If /etc/nsswitch.conf isn't the answer, then try
something like this:
strace -o /tmp/rc5.trace ./rc5des -fetch
This will create a (large) file called /tmp/rc5.trace which shows a log
of all the system calls made during the run of the program. You can
then analyze it to see what it did. For example,
egrep 'stat|open' /tmp/rc5.trace
will show all the lines that have 'stat' or 'open' on them. This should
show you all the files that the program is looking for. It takes some
practice to be able to understand the output completely, but often this
will give you important information about what is going wrong.
