Pkgng | Compiled versions download

[Jos Chrispijn]

   Just found out that updating my ports with pkg is causing an issue: it
   downloads compiled versions.
   The problem I get now is that pe with Postfix, TLD and Dovecot are not
   part of that compilation - in other words I have to reinstall before it
   works.
   Is there a way of compiling the port(s) after downloaden (sorry, pkg
   nub online)?
   Best regards,
