You have the grep port installed. db46 (and a whole lot of other  
software) uses grep at some point during configuration and doesn't  
care what version of grep is used, therefore there is no dependency on  
the grep port. To be most correct, the port should list  
"bin:grep:grep" as a build dependency, but probably half our tree has  
that issue, and grep isn't the only culprit: gawk and gsed are common  
offenders too.

grep needs libiconv, and your libiconv has already been rebuilt as 64- 
bit but your grep is still 32-bit. Therefore your grep cannot use it,  
and tries to use the system's libiconv in /usr/lib. But the system's  
libiconv is too old, hence the error:

The solution is to upgrade grep (and gawk and gsed if you have them)  
first. Then clean db46 (or whatever other port you got stuck on) and  
try again. I will add this information to the Migration wiki page.
