emerge x11-libs/cairo-1.0.2 fails to emerge because of a HUGE string of XPath errors. I believe there is another bug on this site that may be associated with it (109974) but there isn't enough information in that bug report for me to tell. Anyways, I am including the text of the errors in the Actual Results section. Be forewarned; this is a huge entry! Reproducible: Always Steps to Reproduce: 1. emerge -u gimp # updating to 2.2.8-r1, apparently requires emerging cairo-1.0.2 first Actual Results: It downloaded all the sources without a hitch and began compiling well, and then this massiveness of errors happened: cd . && gtkdoc-mktmpl --module=cairo WARNING: No declaration found for: CAIRO_VERSION_STRING ============================================================================= WARNING: 1 unused declarations.

No, it has nothing to do with bug #109974, which is just about dependancies. Yours is a problem with gtkdoc. A quick and dirty fix would be to 'USE="-doc" emerge -av cairo' while this issue with gtkdoc isn't solved.
Have you tried to upgrade to dev-libs/libxslt-1.1.15?
(In reply to comment #2) > Have you tried to upgrade to dev-libs/libxslt-1.1.15? > I had experienced same errors and the installation of dev-libs/libxslt-1.1.15 solved the problem. (should libxslt be a dependency..?)
Resolving as invalid, not because it wasn't a valid bug, but because the bug was not in cairo.
