ahh guys, i figured it out, had a friend teach me!
just so 'yall know, heres some instructions for anyone in need:
in ssh, on linux, do: /scripts/easyphp
select option 6 when you come to a menu.
go to the php option once your in the main setup.
un-check your current ver, looks like: (*) 4.4.4, so select that, and hit enter.
the * should be gone,
now select the version you would like, and the start should appear.
then hit exit, then exit again, and yes to saving, and it'll start building!
note: it takes a 'lil while to build (about 30 - 45 min)
