I have tested it on my two machines at home. Both "lived" ones. On one I 
had problems, but I did not follow that procedure exactly.

On the laptop everything went definitely smoother.

The first backup things that comes to mind is, one can always reinstall 
libiconv (removing IGNORE), that should allow old binaries to run. I 
don't suggest updating the other ports while libiconv is installed 
though, since the include files will conflict and ports could link to 
the por5ts libiconv instead of the base one.

As I told AN, preserving libiconv.so in /usr/local/lib/compat/pkg and 
then removing the package could help, by allowing the machine to work in 
a "mixed world". Can you try that?

The biggest problem is usually libtool, pulling in old .la files still 
referencing the non existing libiconv.la file. I don't know of any 
solution to that. I had to resort to manually listing offending la files 
and recompiling the owning package. Not optimal :(

I am willing to add further information to the UPDATING entry, but I 
need people with different scenarios to test and report the success of 
the strategies.

Obviously the last resort strategy is deinstalling all ports and 
reinstalling them, which I agree is terrible.
