Greetings,
yesterday evening I ran into a problem involving packages "=media-libs/ libraw-0.21.2" and "=media-libs/libcdr-0.1.8", "emerge", the binhost, "revdep-rebuild", and possibly also the configuration of my rig. The problem is reliably reproducible here using six commands:
$ sudo revdep-rebuild --ignore --nocolor --pretend --verbose
* This is the new python coded version

* The original revdep-rebuild script is installed as revdep-rebuild.sh

* /usr/lib64/libraw.so.23.0.0 -> media-libs/libraw-0.21.2
This is an interesting claim, huh. It looks like this package was built
some time ago, and links to
/usr/lib64/liblcms2_fast_float.so
which does exist, by the way. I think revdep-rebuild is incorrect here.
It is a symlink to /usr/lib64/liblcms2_fast_float.so.2, which also
exists, so this package doesn't need to be rebuilt.
That being said, it's quite confusing that the linker didn't resolve the symlink as it's supposed to. In fact if I build it today, it *does*.
This is technically vulnerable to ABI breakage in the future.
... or would be, if the plugin got used at all. Libtool as usual loses -Wl,--as-needed, pfft.
Does anybody out there have an idea why these two packages are not in- stallable from the binhost or what else is going wrong here?
They are "installable", as portage will install them with --getbinpkg :) whether or not revdep-rebuild then complains about them. Maybe there is something we can do about that though.
