How can I install Plone-2.5.2 correctly on Ubuntu?

I'm trying to install Plone-2.5.2 from a Unified Installer on Ubuntu because I need to test migration.
Unfortunately, I'm having trouble trying to install it to a custom path instead of it installing in 'opt'.
When it installs in 'opt', I'm getting all sorts of permissions error where I can't edit, copy, or paste without going in the terminal and using sudo.

There's variables to change things around in Am I supposed to change those?

This is the Unified Installer I was using:

I'm sorry, I can only help you with my buildout-based installation..
You can try the tar.gz from my buildout

You need an python2.4 installed (maybe helps)
than you can create an virtualenv

$ python2.4/bin/virtualenv-2.4 --clear .
$ ./bin/pip install setuptools==1.4.2 zc.buildout==1.7.1


newest = false
find-links +=

parts =
#    omelette

versions = versions

eggs =

recipe = plone.recipe.zope2instance
zope2-location = ${zope2:location}
debug-mode = on
http-address =
user = admin:admin
verbose-security = on
deprecation-warnings = on
zope-conf-additional =
    locale en_US.UTF-8
eggs =
# e.g. zcml = my.package my.other.package
zcml =

products =

# For more information on this step and configuration options see:
recipe = plone.recipe.zope2install
fake-zope-eggs = true
additional-fake-eggs =
url =

# For more information on this step and configuration options see:
recipe = plone.recipe.distros
urls =
nested-packages =
version-suffix-packages =

recipe = plone.recipe.distros
urls =
nested-packages = Plone-2.5.5.tar.gz
version-suffix-packages = Plone-2.5.5.tar.gz

# installs links to all installed packages to 'parts/omelette'
recipe = collective.recipe.omelette
eggs = ${buildout:eggs}
location = ${buildout:directory}/packages

Pillow = 1.7.8
# plone.recipe.zope2install = 3.3
plone.recipe.zope2install = 2.6
# plone.recipe.zope2instance = 3.10
plone.recipe.zope2instance = 3.6
setuptools = 1.4.2
zc.buildout = 1.7.1

Please disregard what I said before. It turns out the previous site was built with buildout and not Unified installer.
