How so? If svn src and rebuild everything. Do you mean ports?

Typical src build is:

svn co svn://svn.pki2.com/base/stable/9/ /disk-1/src
cd /usr/src; make -j65 buildworld
make installworld
yes | make delete-old
yes | make delete-old-libs
mergemaster
cd /sys/amd64/conf/
./mkconfig.pl SMUNI.in 
config SMUNI
cd ../compile/SMUNI
make cleandepend && make depend && make
make install

That's fairly straight forward.
