Hi, I put my experimental giac spkg here:
http://sage.math.washington.edu/home/wstein/patches/giac-20100717.spkg To build it you have to "sage -f -m giac-20100717". Then "sage -sh", then delete the file it complains about (repeat, lather), type "make install", etc. Note that there are a *ton* of system-wide dependencies needed to get these to build. I installed them all on redhawk.math.washington.edu, which sagemath-users have access to. Anyway, the cool thing is that this package is possible to build, and does let one replicate Parisse's benchmarks with something built from source (not a binary). Cool.
