One can complain a bit that MacTeX installs x86_64-darwin  binaries on
SL even if it is not 64-bit machine capable (as my intel
pre-Core-Duo-2 MacBookPro) but in comparison with the size of TL it is
only 5%. I suspect that simply deleting some TeX binaries is a kind of
experiment about which Adam Savage suggests "Never try it at home" :-)
