Bugzilla Bug 189691

The new sobby ebuild uses built_with_use without inheriting eutils, this causes
the following error when emerging with avahi in USE (note the top line):

/usr/portage/net-misc/sobby/sobby-0.4.3.ebuild: line 21: built_with_use:
command not found
 * Please reinstall net-libs/obby with the avahi USE-flag enabled
 * for zeroconf/DNS-SD support or disable it for this package.
 * 
 * ERROR: net-misc/sobby-0.4.3 failed.
 * Call stack:
 *   ebuild.sh, line 1670:   Called dyn_setup
 *   ebuild.sh, line 719:   Called qa_call 'pkg_setup'
 *   ebuild.sh, line 44:   Called pkg_setup
 *   sobby-0.4.3.ebuild, line 24:   Called die
 * 
 * Missing 'avahi' USE-flag for net-libs/obby

Simply adding inherit eutils to the top of the ebuild fixes the problem here.

Sorry, that was my fault. Cleaned up too much :-)
Fixed in CVS with the version bump. Thanks for reporting.
