There isn't necessarily a problem at all. An SSL or TLS implementation
is not guaranteed to support all ciphersuites so if the two sides do not
share a common ciphersuite a handshake error will occur.

Current versions of Netscape, MSIE for example do not support DHE
ciphersuites at all. 

[BTW This is likely to change in future because I've donated DHE code to
the Mozilla project so it should support DHE ciphersuites at some point]
