Hi, I use centos as it is stable and provides all the software that is needed for everyday use. However, sometimes I would like to use fresh software that is not available as a package. Compiling from source is indeed an option but because centos uses oldish sources not only the sought package should be built but a lot of other packages. An idea is to build it in a directory, as much independent as it is possible from the installed libraries on the centos installation. Is there an automated build system for such an endeavour? - Gergely
