I see the following in the Configure file for openssl-0.9.8h:

  my $default_depflags = "-DOPENSSL_NO_CAMELLIA -DOPENSSL_NO_CMS -DOPENSSL_NO_GMP -DOPENSSL_NO_MDC2 -DOPENSSL_NO_RC5 -DOPENSSL_NO_RFC3779 -DOPENSSL_NO_SEED -DOPENSSL_NO_TLSEXT ";my $default_depflags = "-DOPENSSL_NO_CAMELLIA -DOPENSSL_NO_CMS -DOPENSSL_NO_GMP 

I don't know why this would be, but I infer that the function hopenssl
was looking for is commonly missing in SSL builds.
