Interesting, I got this too, when emerging first time. Then I started some debugging to see what could cause it, unmerged dev-lang/v8 to make sure the system lib was not used, emerged this cleanly and couldn't reproduce. I made additional checks to ensure the system lib doesn't get used for testing (which could cause such failures), but couldn't find anything suspicious. What was your previous version of v8? Is this bug still reproducible on your system?
I'm upgrading from v8-3.9.24.7. I can still reproduce it. Anything you would like me to try?
I can also confirm that the test passes once the previous version has been *completely* removed. The preserve-libs feature kept /usr/lib64/libv8.so.3.9.24; I had to manually remove this file before the test would pass.
Now I am unable to reproduce this, even after downgrading v8 and attempting another upgrade.
I'm unable to repro with more recent v8. Maybe that was a one-time fluke, I couldn't find something obviously wrong with the build system.
