Info provide by Martin Vermeer (martin.vermeer at hut.fi):

The latest openssh didn't build for me apparently because of my old
openssl (openssl-0.9.5a-2.6.x installed as rpm). I managed to fix and
get it working, however. The fix is as follows (sorry for not having a
patch -- if this is of interest to you I could checkout the CVS and
make one): 

1) in cipher-aes.c add the stanza

#if OPENSSL_VERSION_NUMBER < 0x00906000L
#define SSH_OLD_EVP
#endif

to the beginning of the file (under #include "includes.h")

2) in cipher-ctr.c do the same (under #include "xmalloc.h")

3) in cipher-3des1.c, do the same

4) in cipher-ctr.c line 97, replace key_len by buf_len 
[Is this right? No idea. key_len doesn't compile.]

5) in cipher-ctr.c, add the following conditional around 'flags':

#ifndef SSH_OLD_EVP
    aes_ctr.flags = EVP_CIPH_CBC_MODE | EVP_CIPH_VARIABLE_LENGTH |
        EVP_CIPH_ALWAYS_CALL_INIT | EVP_CIPH_CUSTOM_IV;
#endif

That's it. Apparently this was never tested as RH 6.2 is getting old :-(
