Details of package collisions are not included in the install log. This results in the log being useless in the case of a failure due to package collisions, but the user is still directed to submit it for bug reports. From the install section of the emerge: >>> Installing (218 of 265) kde-misc/krename-4.0.1 * checking 12 files for package collisions * 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.

The message refers to 'elog' messages, which are actually separate logs. For example, you should see the collision message in /var/log/portage/elog/summary.log. I guess we can include the collision message in the build log as well, though.
This is fixed in svn r14600.
This is fixed in 2.1.7.2 and 2.2_rc47.
