Buildpkg is a package build system. It gives you the opportunity to create package system (rpm, dpkg, etc.) independent descriptions (.def) which can be used to create binary packages on every system. It can be also used to track installations and create packages of the installed files. If you want more safety, you can use the 'jail' feature. In this mode a chroot-ed environment will be created from the (configurable) list of programs and the installation will be done here. Besides Linux, Solaris/SunOS, and FreeBSD packages are also supported.
