I suppose SAGE ship PARI/GP 2.2.12 which include some asm files that darwin assembler cannot parse. On the other hand, PARI/GP CVS (and upcoming 2.2.13) does not include such files so should work fine with darwin. > Bill: is the asm code really useless? There were actually two kind of asm files: 1) The 'gcc asm inline' ones. Those are used in practice, make things faster and work fine with darwin. 2) The .s files. Thoses were not used in practice, did not make things any faster when they were actually used and did not work with darwin. We removed 2) in CVS but we kept 1). The flag --kernel=none cause PARI/GP to not use both 1) and 2) so cause a slowdown. Cheers, Bill.
