cannot install 'lv +with_xz' directly

On MacPorts 1.9.0-beta1, 'sudo port install lv +with_xz' fails to activate due to conflict between lzmautils and xz-devel.

Error: Target org.macports.activate returned: Image error: /opt/local/bin/lzcat is being used by the active lzmautils port.  Please deactivate this port first, or use 'port -f activate xz-devel' to force the activation.
Log for xz-devel is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_archivers_xz-devel/main.log
Error: The following dependencies failed to build: xz-devel
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

To avoid this issue, I had to install xz-devel at first.

$ sudo port -f uninstall installed
$ sudo port install xz-devel
$ sudo port install lv +with_xz

Anyway, this issue doesn't occur if MacPorts is 1.8.2.

Again, I don't see why this would be any different between MacPorts 1.9 and 1.8. The ports do conflict. All MacPorts can do is issue an error.

[jmroot (Joshua Root)]

This is really a problem with the ports involved; the conflicting lzmautils port is required by a different dependency of lv.

If you have the beta version of XZ Utils installed, there is no need for LZMA Utils since it replaces those. If you don't want to extract .xz, but *only* want to extract .lzma, then it still "works". Which is why MacPorts base uses it:

use_lzma        yes
->  depends_extract-append bin:lzma:lzmautils

use_xz          yes
->  depends_extract-append bin:xz:xz-devel

For the ports mentioned above, as long as "xz-devel" is installed *before* "texinfo" it won't try to install lzmautils. I don't either see why there would be any difference between 1.8 and 1.9, in this regard.

Seems that r67384 fixes this problem, as well as #24808.
