So let me ask this, "Do you like to have gls, guniq in your /opt/

Is there any case that removing "g" prefix causes any problems?
I think they are by default off because you expect ls from BSD
and not
from GNU on Mac OS X by default. It might break other shell
scripts.
I doubt it.
I think almost all scripts starts with "#!/bin/bla" or "#!/usr/bin/
bla"
so installing GNUs in /opt/local/bin will not break anything,
if you don't run a script like "sh somescript.sh" or "awk -f
somescript.awk"
Imagine a bash script using ls, but it is expecting BSD ls, not GNU
ls.
It may fail because the options of these programs are different
(except
the POSIX subset of arguments).
That makes sense, but in that case,
shell scripter should specify exact bin path
like
LS=/bin/ls # BSD ls
$LS -bsdoption something" instead.
And you can easily force scripts to which ls to use like below.
$ PATH=/usr/bin:/bin:/usr/sbin:/sbin somescript.sh
In default case (g prefix), there's no easy way to fix this
other than renaming bins in script or re-installing
coreutils with "with_default_names" just as you suggested me.
Well, in a perfect world everything "should be" like it isn't in the
real world. In a perfect world your shell script would have been
prepared for 'seq' to not exist, too. ;)
There are quite a few things that start to break if you use e.g.
coreutils without the "g" prefix. Search the bug tracker if you are
interested in what exactly breaks; I had tickets where the "install"
program of coreutils behaved different and lead to errors in my ports
-- very nasty to track down.
If you want or have to GNU-ify your system, I'd recommend to either
add aliases for the gnu tools (alias install='ginstall') or to symlink
the gnutools to a new "bin" directory with the names you want them to
have.
Perhaps we could add this as a feature to the ports: Have a directory
$prefix/gnu/[s]bin where the GNU tools would appear with their
original name. Then the GNU fans could add those two directories to
their path (before the standard macport directories).
