To be clear: it's not a libintl issue; it's an issue of any software  
installing a binary-incompatible newer version, and other ports that  
depend on that software having to be rebuilt, and MacPorts not having  
any built-in facility for doing so.

"port -f install" is not recommended. Please see this ticket:

http://trac.macports.org/projects/macports/ticket/12989

-f tells install (and upgrade) to forcibly rebuild all the  
dependencies, each time they're encountered, which could be many many  
times. You don't want this.

There's no need in your case to force the install. It'll go just fine  
without forcing.

So you have a broken libiconv in /usr/local/lib.

You had a broken libiconv library directly in /usr/local and most  
software looks in /usr/local for dependencies when building. We have  
not yet found a satisfactory way to prevent software from doing this.  
Therefore, I recommend you do not have any software directly in /usr/ 
local if you want to use MacPorts. (/usr/local/anything is fine, so / 
usr/local/ada is not a problem.)

Make a new directory /usr/local-off and move all the standard  
directories (bin, etc, include, lib, libexec, man, sbin, share, var)  
out of /usr/local and into /usr/local-off. Now any software in  
MacPorts that was built against those rogue libraries should start  
breaking. When it does, rebuild that software, using:

sudo port -ncuf upgrade foo

You can also use "otool -L" against any of the libraries and binaries  
in /opt/local and see if anything in /usr/local shows up. If it does,  
rebuild the port that installed that library or binary. To find out  
what port that is, say e.g. "port provides /opt/local/lib/foo. 
1.2.3.dylib"
