Erm... no, or basically yes. :-)
First of all, the example here refers to portupgrade, not
to portmaster.
The DISABLE_CONFLICTS variable is only required where
something is built from source. By using packages, you
can even _force_ installation of (maybe conflicting)
packages, implying of course that this may cause damage.
In _worst_ cases, there's the option to forcedly deinstall
packages and then re-install them (in a newer version),
this may be useful when the upgrade path is too much
trouble.
Coming back to that example: If you order portmaster to
upgrade perl, you will traditionally also upgrade all
ports depending on it. And if this is possible via
packages (-P, -PP), it will "reconstruct" the dependencies
properly so all programs can use the new perl version.
However, as I've turned into a "compile guy" due to
sufficient hardware, I usually use source-based updates
when needed. I don't update my home system very often,
because I'd like to keep it in a functional state. :-)
So I've not come across that particular update yet, as
I still have perl-threaded-5.10.1_4 installed, and there's
nothing here that requires 5.12 or 5.14.
When you choose to use portupgrade instead of portmaster,
it's a good choice to always run "pkgdb -aF" before and
after anything you do (e. g. also "around" a pkg_add -r
command). I've been using portupgrade in the past, but
today I prefer "just ports" (home) and portmaster (work).
