Hello ! As it's recommanded, I give here the error I get when I try to compile sage 5.10 on my MacBook pro :

Instead, the following commands setup all environment variables correctly and load a subshell for you to debug the error: (cd '/Applications/sage-5.10/spkg/build/matplotlib-1.2.1' && '/Applications/sage-5.10/sage' --sh) When you are done debugging, you can type "exit" to leave the subshell. ************************************************************************ make[2]: *** [/Applications/sage-5.10/spkg/installed/matplotlib-1.2.1] Error 1 make[1]: *** [all] Error 2 real 204m19.622s user 163m9.197s sys 17m16.147s *************************************************************** Error building Sage.
