Acrobat 5 install

[luckysnafu]

I am trying to install Acrobat 5 and after i unpack the tar file i try the ./INSTALL and it always gives me the same error

./INSTALL: ed: command not found
ERROR installing y/bin/acroread

Does anybody know why i am getting this error? I get the same error when trying to install acrobat 4 as well.

i think you are missing ed.

DESCRIPTION
ed is a line-oriented text editor. It is used to create, display, modify and oth_
erwise manipulate text files. red is a restricted ed: it can only edit files in
the current directory and cannot execute shell commands.

it (the install sccript) is probably using it to display the EULA.

install ed and the error should go away.
