thanks for agreeing :)

ok, let's try .. starting at 1005280k ..

Putorius:~ count$ sudo port clean --distfiles all
Error: clean does not accept --distfiles
oops. (MacPorts 1.710) ... --dist seems to be it ;)
.. brings me down to 900384k ..

okay, this seems to be it - I'd like to strongly suggest making this the
default for non-developers ...

okay, this leaves me at 561884 - not much dramatic/really unneeded
Documenting all this would really help others, I think :)

I totally agree. Debian solves this by offering a 'localepurge' package,
which basically allows you to give a list of languages you need (i.e.
which are useful to you ;)), and just has a install-hook which takes
care of throwing away all other localization files.
Though, it's description reads:
Description: Automagically remove unnecessary locale data
This is just a simple script to recover diskspace wasted for unneeded
locale files and localized man pages. It will automagically be invoked
upon completion of any apt installation run.
Please note, that this tool is a hack which is *not* integrated with
Debian's package management system and therefore is not for the faint
of heart. This program interferes with the Debian package management
and does provoke strange, but usually harmless, behaviour of programs
related with apt/dpkg like dpkg-repack, debsums, reportbug, etc.
Responsibility for its usage and possible breakage of your system
therefore lies in the sysadmin's (your) hands.
Please definitely do abstain from reporting any such bugs blaming
localepurge if you break your system by using it. If you don't know
what you are doing and can't handle any resulting breakage on your own
then please simply don't use this package.

okay, good to know! - thanks for the help :)
In theory, theory and practice are the same. In practice, they’re not.
