The INDEX file should match the snapshot of the ports tree which you downloaded using portsnap, if I have understood the mechanism correctly. For updates using SVN this _might_ not be the case, but a mismatch would be reported anyway, so it's easy to try out. > To overload this thread: > I wanted to build php56 and let it fly.

That depends on the dependency version number, or if a port requires an "exact" or "at least" version of a dependency. You can run the # make missing command before you start the build - it will list the things that are missing (or not matching). In case you need to restart a build, # make clean # make # make install is the recommended approach. Running with "partially built stuff" often isn't a good idea and could lead to non-working results, as far as I understand. But you probably don't need to rebuild all the dependencies, so "make clean-recursive" usually isn't needed. > Precompiled packages might be simpler, but if the prebuild binary does > not have > all the extensions and features that I want, and has many that I > don't need or want. That is the main "problem" with precompiled ports: They are being generated from the _default_ options of the port which are set by its maintainer. This will fit in many cases, but not in all cases, and if _your_ case is different, you need to set your individual compile options (which the binary package doesn't reflect). In conclusion, those options might change which dependencies a port requires. As you will see, "make missing" could then lead to a different result. As far as I know, there will be "flavors" of ports that will deal with this "problem", but it's not there yet. Just imagine how many different packages you would need for a port with n options, and then try to find out how to _name_ those... ;-) Typical candidates for this scenario are, for example, multi- media software like mplayer or mencoder, where options might be "I want _all_ codes, even those which are 'illegal' in my country" up to "I just want a very small subset of codecs supported, and I want certain specific compiler optimization flags to make the encoder run on a low-spec system". This is something you usually solve by using ports, manually set options, and maybe even Makefile.local. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
