I'm looking to build the 'vim' editor from source using pkgsrc. Can you outline the general requirements for building packages, explain how to ensure all necessary source files are downloaded, and provide the basic command for building and installing 'vim'? Also, what is an important note regarding the 'make' command for non-NetBSD systems, and where would I typically configure persistent settings like `PREFIX` or `DISTFILES`?
Navigate to the main index of 'The pkgsrc guide' (pkgsrc.org/guide/). Click on '5. Using pkgsrc' (ID 132). Click on '5.2. Building packages from source' (ID 166). From '5.2.1. Requirements' (ID 171), identify the general requirements for building packages. From '5.2.2. Fetching distfiles' (ID 174), identify how to ensure all necessary distribution files are downloaded. From '5.2.3. How to build and install' (ID 177), identify the basic command to build and install a package and any important notes regarding the 'make' command for non-NetBSD systems. Scan the text for mentions of configuration files like 'mk.conf' to determine where persistent settings are typically configured. Synthesize all gathered information to answer the task.
The agent successfully navigates to the 'Building packages from source' section. The agent identifies and states that a working C compiler is a general requirement, and for NetBSD, 'comp' and 'text' distribution sets (plus 'xbase' and 'xcomp' for X11) are needed. The agent explains that `make distfiles` is the command to ensure all necessary source files are downloaded into the `DISTFILES` directory. The agent states that `make install` is the command to build and install a package. The agent notes that for non-NetBSD systems or when using bootstrap, `bmake` should be used instead of `make`. The agent identifies that persistent settings like `PREFIX` or `DISTFILES` are typically configured by setting variables in the `mk.conf` file.
