There are three options to solve this:
1. pass no-asm to ./Configure,
2. patch asm/alpha.s to include bn_div_words, or,
3. start with 2 above, then find an axp guru and optimize things.
In case you take the third way, please send us the results :)
I'll include the original article from Holger Reiff who submitted
the patch, and, the patch itself:

Subject: Patch: BN_div_words in asm/alpha.s
Reply-To: [EMAIL PROTECTED]
Hi all,
here is a patch for adding bn_div_words to asm/alpha.s. It got lost
somehow, but without the assembler version won't compile.
I'm not entirely familiar with the internal working of openssl, but to
my untrained eye bn_asm.c:bn_div_words and bn_mulw.c:bn_div64 are
looking suspiciously similar. Is there a special reason for it or can we
just scrap one version ?
(I suspect that's also why bn_div_words does not appear in asm/alpha.s;
it just got renamed to bn_div64 hoping that all functions would call
this and not bn_div_words. Evolutionary programming :-).
HTH,
Hannes
