I can certainly do that.  It would help to know a little more than the above, 
since the only "bezout" files I could find are text files that (I don't think) 
get compiled.

Do we know what ".c" files are involved?  Could the problem like with a library 
(whose initials might once have been GPM)?  I have not delved into the innards 
of pari enough to be able to sort this out quickly on my own.

Anything more specific than "it breaks" will get a lot more attention from 
Apple, and I think Apple knows that their compiler suite for 10.7 has 
significant issues.
