This may be true for some specific implementations of DES, but it need
not be. For example, I believe the ufc-crypt implementation of DES
works correctly without the aid of endian-based #ifdef's or other such
accommodations. This is definitely true of a DES implementation I
once wrote myself.
Perhaps your difficulty lies in the transmission of the encrypted data
between the two architectures. This was solved long ago at the TCP/IP
layers by the specification of of a standard byte order for
transmitted data. You might start with the htonl(3) man page for more
information.
