:-)
On the front page of gentoo.org several blogs are reference that mention this
issue. In one of them, the author shows evidence that the same binary was
trying to link at one point to a 32 bit lib and at another point link to a 64
bit lib..... All random of course, causing no end of mysterious failures, and
explains why some people had success re-merging cairo, other with something
else ....
Truly bizarre. But it might go a ways to explaining why your 32 bit systems
were unaffected?
