I've got the same problem with the newest ebuild: jack-rack-1.4.8_rc1 Seems the patch out of comment #1 isn't already included.
LDFLAGS="-lm" emerge jack-rack Worked for me without errors, too. But this is just a workaround, not the solution: The package, better the source, has to be fixed in the way, giving explicitly the needed libs in the right order to the linker command, so that underlinking will work in the future. This workaround will create superfluous work in the future, because of revdep-rebuild commands now needed when underlying libraries will change.
wouldn't it work if it was added to the ebuild?
fixed in portage for version 1.4.8_rc1 without revbump by adding the missing -lm: http://sources.gentoo.org/viewvc.cgi/gentoo-x86/media-sound/jack-rack/jack-rack-1.4.8_rc1.ebuild?r1=1.3&r2=1.4 http://sources.gentoo.org/viewvc.cgi/gentoo-x86/media-sound/jack-rack/files/jack-rack-1.4.8_rc1-underlinking.patch?rev=1.1&content-type=text/plain
