Have you unmerged previous version properly?
I was upgrading openexr, so no - previous version was not yet unmerged. I rebuilt 1.6.0 with the "examples"-flag enabled and it worked. I guess the build process is erroneously using the system libraries instead of those just built.
One should block the other, I think: Index: openexr-1.6.0.ebuild =================================================================== RCS file: /var/cvsroot/gentoo-x86/media-libs/openexr/openexr-1.6.0.ebuild,v retrieving revision 1.3 diff -u -B -r1.3 openexr-1.6.0.ebuild --- openexr-1.6.0.ebuild 14 Sep 2007 04:51:57 -0000 1.3 +++ openexr-1.6.0.ebuild 17 Sep 2007 14:46:46 -0000 @@ -13,7 +13,8 @@ RDEPEND="media-libs/ilmbase" DEPEND="${RDEPEND} - dev-util/pkgconfig" + dev-util/pkgconfig + !<${CATEGORY}/${P}" src_unpack() { unpack ${A}

Yep, could you please explain me how you did manage to upgrade to 1.6.0 without unmerging 1.4 ?
What do you mean? Normal procedure is to unmerge the package after the new one is merged during upgrades. That's how emerge and paludis works anyway afaik.

That's how emerge and paludis works anyway afaik. > yes but ilmbase is needed by openexr 1.6 and ilmbase will collide with openexr 1.4, so ilmbase and openexr < 1.5 block themselves this is not the best way to do this, but as upstream has split openexr in several packages, this requires us to do like that. As a consequence you should be required to unmerge openexr 1.4 *before* merging 1.6. And you appear not having been required to do so :/
Ah, now I'm beginning to understand what the merge problem is. I still believe it's wrong to build examples using system installed libs and not the ones about to be merged. Anyway, I've tested emerge and paludis side-by-side and emerge catches the block but paludis somehow does not (unless the ilmbase package is specified on the commandline along with openexr). That seems like a flaw in paludis. Emerge: http://rafb.net/p/hJfbnj13.html Paludis: http://rafb.net/p/RB6wbc53.html
