It looks pretty, but I wouldn't call it organized. You've got lots of data duplication -- why bother storing nginx in an array named nginx -- and if both things get the same prefix and make options, why not split that out too? And you're not looping things you can loop. And you're desperately avoiding splitting when it's something that could replace 80% of your code here. And using arrays means you end up spitting out ${ARR[1]} and ${ARR[2]} everywhere instead of using meaningful variable names. Why is '-j 4' the third element of your array and not the second, fifth, ninth? Only the original programmer knows.
In short this code will be as hard for you to read later as it was for me to read now.
I'd still split the URL's out since they're big and unwieldy.
Code:
MAKE_OPTS="-j 4"
CONFIG_OPTS="--prefix=/opt"
nginx="http://nginx.org/download/nginx-1.2.2.tar.gz"
supervisor="http://pypi.python.org/packages/source/s/supervisor/supervisor-3.0a12.tar.gz"
for PACKAGE in nginx supervisor
do
echo wget "${!PACKAGE}"
echo configure $CONFIG_OPTS ... # Note not quoted
echo make $MAKE_OPTS ... # Note not quoted
done
I suppose you could have variables overriding the default $CONFIG_OPTS and $MAKE_OPTS for a particular package. If they're blank, use the default options, if they're not, use them instead.

script
script(1) User Commands script(1)NAME
script - make record of a terminal session
SYNOPSIS
script [-a] [filename]
DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
record is saved in the file typescript. See WARNINGS.
The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
when the forked shell exits or when Control-d is typed.
OPTIONS
The following option is supported:
-a Appends the session record to filename, rather than overwriting it.
NOTES
script places everything that appears on the screen in filename, including prompts.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
