dev-ruby/json-1.8.1 is currently installed (with splitdebug and -Wl,--build-id). dev-lang/ruby-2.0.0_p247-r1 was installed without LDFLAGS=-Wl,--build-id. Attempting to install dev-lang/ruby-2.0.0_p247-r2 with LDFLAGS=-Wl,--build-id results in the following collision: * 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). See * http://wiki.gentoo.org/wiki/Knowledge_Base:Blockers for tips on how to * solve the problem. And once again, please do NOT file a bug report * unless you have completely understood the above message. * * Detected file collision(s): * * /usr/lib/debug/.build-id/e1/798f66786ef66d2f0d4cec1fbaca463fa32b72.debug * /usr/lib/debug/.build-id/e1/798f66786ef66d2f0d4cec1fbaca463fa32b72 * * Searching all installed packages for file collisions... * * Press Ctrl-C to Stop * * dev-ruby/json-1.8.1:0::gentoo * /usr/lib/debug/.build-id/e1/798f66786ef66d2f0d4cec1fbaca463fa32b72 * /usr/lib/debug/.build-id/e1/798f66786ef66d2f0d4cec1fbaca463fa32b72.debug * * Package 'dev-lang/ruby-2.0.0_p247-r2' NOT merged due to file * collisions.

I've begun using COLLISION_IGNORE="/usr/lib/debug/.build-id/*/*" as a workaround.
Must be one of these (dev-lang/ruby): /usr/lib64/ruby/2.0.0/x86_64-linux/json/ext/parser.so /usr/lib64/ruby/2.0.0/x86_64-linux/json/ext/generator.so colliding with one of these (dev-ruby/json): /usr/lib64/ruby/gems/2.0.0/gems/json-1.8.0/lib/json/ext/parser.so /usr/lib64/ruby/gems/2.0.0/gems/json-1.8.0/lib/json/ext/generator.so Which (paths might differ)?
At the moment with ruby-2.0.0_p353-r2 and json-1.8.1 installed none of those files share a buildid, nor do they have the build id I attached to this report.
We don't properly unbundle the json gem from the ruby code, even though we already depend on the external version. We'll need to test bootstrapping a new version if we remove this. I'm not sure if it is completely possible. Whether or not this actually causes a problem depends on your combination of bundled code in the ruby release and the gem installed.
We are properly unbundling the json code from the ruby ebuilds, but only at installation time. At that time the build-id files are already generated and given that they don't have normal filenames we cannot unbundle them when we unbundle the rest of the json code. I'm not sure how we can fix this. Hopefully there will be changes in the toolchain class that will help us fix this somehow.
The toolchain.eclass change that caused this has been reverted for now. Please see https://bugs.gentoo.org/show_bug.cgi?id=526144#c5 on how to remedy this for existing systems that are affected.
