>>> Installing (9 of 337) x11-drivers/xf86-input-wacom-0.10.0 * This package will overwrite one or more files that may belong to other * packages (see list below). You can use a command such as `portageq * owners / <filename>` to identify the installed package that owns a * file. If portageq reports that only one package owns a file then do * NOT file a bug report. A bug report is only useful if it identifies at * least two or more packages that are known to install the same file(s). * If a collision occurs and you can not explain where the file came from * then you should simply ignore the collision since there is not enough * information to determine if a real problem exists. Please do NOT file * a bug report at http://bugs.gentoo.org unless you report exactly which * two packages install the same file(s). Once again, please do NOT file * a bug report unless you have completely understood the above message. * * package x11-drivers/xf86-input-wacom-0.10.0 NOT merged * * Detected file collision(s): * * /usr/lib/xorg/modules/input/wacom_drv.so * /usr/lib/debug/usr/lib/xorg/modules/input/wacom_drv.so.debug * * Searching all installed packages for file collisions... * * Press Ctrl-C to Stop * * x11-drivers/linuxwacom-0.8.4_p1 * /usr/lib/debug/usr/lib/xorg/modules/input/wacom_drv.so.debug * /usr/lib/xorg/modules/input/wacom_drv.so * * Package 'x11-drivers/xf86-input-wacom-0.10.0' NOT merged due to file * collisions.

Added blocker in all linuxwacom ebuilds in portage. That should be enough. Thanks
