You can do it 100 times and it will give you the same outcome, normally 
when this happens you remove all ports and build the ones you want, this 
helps in old libs being compiled, Also people do strange things in hopes 
to make things faster an increase of 0.000000001% when adding CPUFLAGS= 
bleh isn't really much to award for and causes issues in the long run. 
Mixing PKGng and Ports causes issues as well. Personally I don't run 
bash as I classify it as a linuxism, but whenever I upgrade I remove all 
my ports and recompile, not using portmaster as it has been known to 
cause problems.

My 2 cents
