That's right.

tested.
I think that's right, too. I don't know much about writing shell scripts,
but this seems to work:
{{{
#!/usr/bin/env bash
INSTALLED="$SAGE_PACKAGES/installed/"
PKG_NAME=`echo "$1" | sed -e "s/\.spkg$//"`
PKG_NAME=`basename "$PKG_NAME"`
PKG_BASE=`echo "$PKG_NAME" | sed -e "s/-.*//"`
cd "$SAGE_PACKAGES/installed"
if [ `echo $PKG_BASE*` ]; then
echo "sage: $PKG_BASE is already installed"
exit 0
fi
}}}
($SAGE_PACKAGES is defined by running "sage -sh".) This script defines
PKG_BASE to be the name of the package without the version number:
everything up to the first hyphen or period, whichever comes first.
