************************************************************************ Please email sage-devel (http://groups.google.com/group/sage-devel) explaining the problem and including the log files /Users/Latisp/github/sage/logs/pkgs/tachyon-0.98.9.p7.log and /Users/Latisp/github/sage/config.log Describe your computer, operating system, etc. If you want to try to fix the problem yourself, *don't* just cd to /Users/Latisp/github/sage/local/var/tmp/sage/build/tachyon-0.98.9.p7 and type 'make' or whatever is appropriate. Instead, the following commands setup all environment variables correctly and load a subshell for you to debug the error: (cd '/Users/Latisp/github/sage/local/var/tmp/sage/build/tachyon-0.98.9.p7' && '/Users/Latisp/github/sage/sage' --buildsh) When you are done debugging, you can type "exit" to leave the subshell. ************************************************************************
