dev-libs/apr (slot 0) and dev-libs/apr (slot 1) cause collisions on the /usr/lib/apr.exp file. I looked at apr.spec that is distributed with both versions and saw that they all contain the following: # Unpackaged files: rm -f $RPM_BUILD_ROOT%{_libdir}/apr.exp I guess this means that the apr ebuilds can be modified like: @@ -46,4 +46,5 @@ src_install() { einstall installbuilddir=${D}/usr/share/apr-1/build + rm -fv ${D}/usr/$(get_libdir)/apr.exp #bogus values pointing at /var/tmp/portage Same goes for apr-util. However, in that case it is aprutil.exp that has to be removed. Actually it should actually be ${D}/usr/lib/apr.exp, as the apr* ebuilds are not get_libdir friendly. I'll submit another bug about that. Patches tested and working.
apr-1.x isn't quite supported, it's more of an experimental ebuild, that will more then likely be rewritten when we start preparing for apache-2.2.
Well, as I did hit this right now, I'm reopening this. It's needed for apache-2.2.x anyway.
Fixed in CVS.
