thank you so much!!! it worked, and the same trick worked for installing database_gap.
i find very odd, this being said, that sage -optional should recommend me to use 4.5.7. And also that the version of sage i have downloaded this very week is not the latest one... incidentally, compiling sage from source (which was also sage 5.5, so not the latest one i guess) also failed, on a recent macbook air with nothing funny to it. It just went erreur fatale: AE/AE.h : No such file or directory compilation terminée. error: command 'gcc' failed with exit status 1 Error building and installing Mercurial anyway, that doesn't really matter. Thanks again!
