One quick comment about pkg upgrading when building from source:

Sometimes it happens that packages dont't build entirely without
pain. For that reason I typically build first and install (as in
upgrade) after the build went ok. 

Therefore I suggest that the removal of the previous version is
deferred until after the build went well. This way you don't run the
risk of ending up with the old version removed and the new version in
