[ptxdist] fix "local -a" + IFS problem

This patch fixes a problem with bash-3.0.x. This old bash versions
doesn't respect IFS when splitting a variable: This costruct doesn't
work:

	foo="bar:baz"
	local -a qux=( ${foo} )
	echo "${foo[@]}"

it prints:

	bar:baz

bash > 3.0.x prints

	bar baz

The correct sequence is to first declare qux as a local array and then
assign it:

	local -a qux
	qux=( ${foo} )
