You want this:
unless ((found)) ; then
plist_deps+=("$subdep")
eval $plist='("${plist_deps[@]}")'
fi
Of course, isn't the variable `plist' supposed to be a reference to
your *string* variable that holds a space-separated list of items? In
that case, the last line should be:
IFS=' ' eval $plist='"${a[*]}"'
