Hi, I wanted to share a script which allows to build Dolfin and its dependencies from source tar balls. It can be found here: broncodev/fenics-pkgbuild-group - NotABug.org: Free code hosting
It uses a collection of PKGBUILD (pacman-based systems like Parabola GNU/Linux). These are mostly step-by-step bash files which can guide you in other systems (a pacman-based system will build in a ${srcdir}, where the sources are placed, and will install to ${pkgdir}; adapt accordingly; broncodev/python-ufl-pkgbuild - NotABug.org: Free code hosting may be a good example to see the basic logic of PKGBUILD).
