You may find /usr/ports/UPDATING entry 20131217: interesting. I think the 
plan here is to have a period of semi-deprecation of some months then at 
some point the 4.1/4.2 ports will cease to exist.

Since 10 is the point where Clang is now the default, as well as some other 
changes (unbind) I decided to do a fresh install from scratch so everything 
would be clean with no cruft left over from pre 10 days. I had hoped that the 
db41/db42 situation would just take care of itself automagically with the 
fresh 10 install, but it did not.


In /usr/src/Makefile:
[...]
#  9.  `make delete-old'
# 10.  `reboot'
# 11.  `make delete-old-libs' (in case no 3rd party program uses them 
anymore)


You should rebuild all ports *first* - prior to doing the 'make delete-old-
libs' after a source based upgrade between major versions (9.x -> so.x)
