I'm curious, does it actually work correctly?

Are there alternatives to the Math::Pari module that can be dropped in to replace it from the perspective of the other Crypt modules?
If there are alternatives then they should be mentioned in the documentation of the modules.
Precisely which modules are these "other Crypt modules" ?

I've updated the main post to reflect a few of the modules with a Math::Pari dependency.

Couldn't spot any evidence that Crypt::DSA needs Math::Pari. But it certainly looks like the others that you've specified do.
Cheers,
Rob

Did you also see this
post from Nicholas Clark.
I don't recall if I followed up with his suggestion there. I do know that I'm still interested in the solution, but have been sidetracked for a while. It is nice to see the subject raised again.

Yes, I saw that one. Unfortunately I have no idea about what to do regarding his suggestion. The c code in the Perl guts is beyond my abilities, though I did look in the source at the code he mentioned.

I did what Nickolas suggested. It compiled fine, but failed horribly at runtime with error messages that don't seem to be related to the fix I made. I also tried another way using PERL_MAGIC_ext, but it resulted in the same issues.
So I guess Math::Pari is relying on more <=5.8 behaviour that has changed in 5.10. I wasn't able to figure out what exactly that is though.

I've tried it with the following patch:
1153c1153
< ((CV*)cv)->sv_any->xiv_u.xivu_iv = numargs; /* XXXX Nasty of
+us... */
---
> ((CV*)cv)->sv_any->xof_off = numargs; /* XXXX Nasty of us...
+*/
1219c1219
< int numargs = ((CV*)cv)->sv_any->xiv_u.xivu_iv; /* XXXX Nasty
+ of us... */
---
> int numargs = ((CV*)cv)->sv_any->xof_off; /* XXXX Nasty of us
+... */
It seems to work but increases the 'Nasty' level | [reply]
