The version tiff-3.9.5-r1 doesn't install any includes or static libraries that other tools could link with. opencv-2.3.0-r1 isn't able to compile because of this. The current ebuild does the following in the install script instead of `make install` from tiff-3.9.5: src_install() { exeinto /usr/$(get_libdir) doexe libtiff/.libs/libtiff$(get_libname 3) use cxx && doexe libtiff/.libs/libtiffxx$(get_libname 3) } This looks like an intention, but if it is like that, the dependencies on tiff should be removed from other ebuilds.
No, it means you added improper entry to your /etc/portage: tiff-3.9.5.ebuild:KEYWORDS="alpha amd64 arm hppa ia64 m68k ~mips ppc ppc64 s390 sh sparc x86 ~sparc-fbsd ~x86-fbsd ~x64-freebsd ~x86-freebsd ~x86-interix ~amd64-linux ~x86-linux ~ppc-macos ~x64-macos ~x86-macos ~sparc-solaris ~x64-solaris ~x86-solaris" ^ This version is stable and pulled for stable users. tiff-3.9.5-r1.ebuild:KEYWORDS="~alpha ~amd64 ~arm ~hppa ~ia64 ~m68k ~mips ~ppc ~ppc64 ~s390 ~sh ~sparc ~x86 ~sparc-fbsd ~x86-fbsd ~x64-freebsd ~x86-freebsd ~x86-interix ~amd64-linux ~x86-linux ~ppc-macos ~x64-macos ~x86-macos ~sparc-solaris ~x64-solaris ~x86-solaris" ^ This one is not being pulled by anything, except sci-chemisty/icm for ~arch users. tiff-4.0.0_beta7.ebuild:KEYWORDS="~alpha ~amd64 ~arm ~hppa ~ia64 ~m68k ~mips ~ppc ~ppc64 ~s390 ~sh ~sparc ~x86 ~sparc-fbsd ~x86-fbsd ~x64-freebsd ~x86-freebsd ~x86-interix ~amd64-linux ~x86-linux ~ppc-macos ~x64-macos ~x86-macos ~m68k-mint ~sparc-solaris ~x64-solaris ~x86-solaris" ^ This one is pulled by default for ~arch users. So fix your /etc/portage, likely package.keywords or package.mask and everything will be OK again. The ebuilds all install correct files. This is exactly how we handle jpeg and png in portage as well
