From a freshly updated (cvs update -dP) source tree:

./build.sh -T ${METEOR_TOOLS} -m sparc tools kernel=GENERIC

echo 'SYSTEM_HEADER_DIR="'"`echo

sed: 1: "s,[": unbalanced brackets ([])

nbgmake: *** [install-gcc] Error 2

(Note I hardcoded the path to "nbsed" in the gcc4/gcc/Makefile.in after
my native sed had problems.  I thought maybe it was a problem with
native sed.  Now I think there is a shell expansion problem.)

Any advice would be appreciated.  I can't build stuff at the moment.
