Does it mean that one needs ports tree or provide custom INDEX in case of custom packages with non default options (different dependencies) to compute order od dependencies? (AFAIK plain pkg_add works without ports tree and INDEX, that's why I am asking) It is related to my idea of extending packages with more metadata, for example OS version + arch, used build options (WITH_ / WITHOUT_ etc.) so one can easily determine "how this package was built". But it seems as not so easy task to me, as I don't know how to get all the options (from /etc/make.conf, environment variables, /var/db/ports, commandline...) and record them to file in useful way. It can be useful in case where I have some backup of packages from many machines, but have not the original environment, where packages were built etc. Miroslav Lachman
