sure, but rpm is traditionally made from the original tarball, and the local distro doesn't ship a 2.52 that I could simply make as a BuildRequirement to reconf just before %configure. So in the end, the real fix is to report it as a bug to the original author and let him make a new tarball. It's been just interesting to see such interactions between the versions, I have some superprojects here on my disk which combine a couple of autoconf'ed projects under a master project that configures them all in one run. The real projects are just in subdirectories like here, and some are old autoconf, some are new generation (it seems some projects have not been converted or they are not that easy to convert). The issues as shown above make it not a nice move to have the superproject to use the new autoconf generation. Personally, for a simple superproject, that isn't needed anyway - the mp4h however has used the toplevel configure to do real configstuff for its src/ subdirectory and it has just added the libltdl/ subdir to gain support from libtool, later on. That brought in the current setup, and since its just libtoolizing, the author has probably opened a trap, and me to hit while trying an rpm. cheers, -- guido http://freespace.sf.net/guidod
