The sys-devel/libtool package has app-arch/lzma-utils listed as a dependancy, but if you have installed app-arch/xz-utils, which is supposed to be a superset of the lzma-utils then the lzma-utils are blocked. I think the libtool ebuild should allow xz-utils to be a substitute for lzma-utils. It would seem that sys-devel/libtool is not the only package that has this issue, running `emerge -eav system' shows sys-apps/coreutils and sys-apps/sandbox also want lzma-utils. Reproducible: Always Steps to Reproduce: 1. Unmerge app-arch/lzma-utils 2. Emerge app-arch/xz-utils 3. Try to reinstall something like sys-devel/libtool Actual Results: Portage complains that xz-utils is blocking lzma-utils. Expected Results: Packages such as sys-devel/libtool to reinstall if I have either of xz-utils or lzma-utils installed. xz-utils is a superset of lzma-utils, so this shouldn't be a problem. Are the lzma-utils required for sys-devel/libtool?
Could you please run 'emerge --info' and paste that into a bugzilla comment for us?

Libtool only uses the external 'lzma' executable in it's "dist-lzma" target to "make" - and i'm not sure too many people will be needing that... There are dozens of packages in the tree at the moment that are similarly broken, as evidenced by Bug #279871 - though most only list a _BUILD_ dependency because their specified archive is compressed in lzma-format. I'm writing this from a very minimalist Funtoo system which has lzma-utils installed (pulled in as a dependency), and if i remove it to allow xz-utils to emerge, it will break 11 currently installed packages because of this little gremlin. An example of one package that WON'T break is sys-kernel/linux-headers, which requires _either_ {,de}compression-package rather than just the older, now obsolete one.
This bug should block bug 279871.
