I don't know much about perl, and even less about delphi, but I am
pretty sure it does not solve the problem of overwriting files from a
package with an installation outside the control of the package
There is no simple solution to the following situation:
- install setuptools from ubuntu -> files get into /usr
- install setuptools from sources into /usr: overwrite files from
the python-setuptools debian package, with an updated version which is
not compatible with the packaged one -> every Ubuntu package depending
on setuptools is now broken. Worse, it may not be possible to rollback
to a working situation.
To make it work, you would have to somehow notify the package
management system about the updated version. But still, the whole
value of a package manager is to have a whole set of packages which
are tested together. Updating packages 'randomly' from 3rd party
sources is inherently against this.

By fighting, I meant that because OS don't always have uptodate
packages you want to depend on, trying to implement a system to update
the packages is backward. The problem is depending on those recent
libraries in the first place if you want to run on many
