Hi,

I would really like a way to echo more information when a die happens so
the users can paste it in their bug report

Only needs a very simple change to ebuild.sh:

--- ebuild.sh.orig      2005-10-04 12:22:38.000000000 +0200
+++ ebuild.sh   2005-10-04 12:26:45.000000000 +0200

        shift 3

        echo "!!! ${*:-(no error message)}" >&2
        echo "!!! If you need support, post the topmost build error, NOT this status message." >&2
        echo >&2
+       extra_die
        exit 1
 }

then in your eclass you can simply go, for example:
extra_die() {
        echo "!!! If you file a bug report, please include the following information:" >&2
        echo "CLASSPATH: ${CLASSPATH}" >&2
        echo "JAVA_HOME: ${JAVA_HOME}" >&2
	blabla
        echo "and offcourse output of emerge --info" >&2
}

can only think about 2 real problems at the moment: circular dies which shouldn't be that hard to avoid using common sense and when multiple eclass define it and are inheritted it'll only show one
