They're not in place for adding dependencies on where symlinks points at, but rather as an identifier for where 'symlink to SONAME ending with .so in filename' is considered as being part of a devel package, hence the devel(soname) provides, with requires added for all devel(SONAME) found under DT_REQUIRED (so it's more dependencies related to what libraries linked at rather than symlinks endpoints to). These are actually quite convenient dependencies added, as it prevents having to manually add dependencies on other -devel packages in the -devel package that it usually tends to depend on. I'm okay with the helper beng disabled by default, but I really don't see any good reason for moving it under #ifdef mandriva, that would be a step away from any attempts at vendor neutral approach IMO. The devel() dependencies are way more useful in real world cooker usage than ie. the pkgconfig() etc. dependencies at least to my experienec.. -- Regards, Per Øyvind ______________________________________________________________________ RPM Package Manager http://rpm5.org Developer Communication List rpm-devel@rpm5.org
