...funny enough I never noticed this obvious mistake, since I never install software directly into my system, while the DEB-build does not use absolute paths... Solution: * SCons has this speical convention that a path prefixed with '#' is resolved relative to the root of the build (where the SConstruct resides) * now we apply this automatically to the two relevant settings ** INSTALLDIR ** TARGDIR * but only (conditionally) if the configured path is relative, not absolute As a consequence, most other hard-coded usages of the '#'-prefix can then be dropped
