Well, you can use

{|io| io.read}

instead of

{|io| io.each {|line|}}

but that will only give you the output from pscp.  And apparently that
contains [] because it's an error message.  You probably want to look at
the other variants of popen to properly evaluate the result code of the
external command and react appropriately.
