Should I rebuild all ports?

[Choy Kho Yee]

I have just upgraded FreeBSD 5.3BETA6 to BETA7.
According to /usr/src/UPDATING, some of the system
libraries have been upgraded, and we should rebuild
all ports if we want to use the new libraries. So,

  1. should I rebuild all ports? (I think it should take one
      whole day...)
  2. If I am to rebuild all ports, what is the command I
      should use?

  Thanks.
