Hi! I've updated my patch for sage plugin. Instead of using the absolute
path directly, I use another function to find the location of the
tm_sage file. This is inspired by the plugin for Scilab.

In my arch, all start file for plugins are installed in
"$TEXMACS_BIN_PATH/bin", but it seems to be different for mac...
