[opentheory-users] Fwd: cannot build opentheory

Rob, the forwarded conversations below from last year may be of
interest for your Poly/ML problem. I thought they were in the list
archive, but apparently not (until now).

I am using SVN r1324 at the moment. I am on 64-bit. I'll happily try
any debug or other options you think would be helpful. In fact I'll
try a larger -H1000 now... it still appears to be stopping at the same
point. (I'll leave it running for another 10 minutes...)
