If an ebuild configures and compiles several versions of particular executables/libraries, it does it in different directories and subsequently installs each variant in the system. The recent changes in both automake and cmake eclasses break these ebuilds in such a way that although all versions will be built, but only the most recently built will be installed since everything is being built in the same directory. Sometimes the build may fail before the installation step (pykde4 case). If such an erroneous build is successful (e.g., fftw), it is possible that dependent programs (e.g., ambertools or gromacs) fail to build correctly. The simplest solution is to change AUTOTOOLS_BUILD_DIR and CMAKE_BUILD_DIR to BUILD_DIR in all ebuilds that need it. The developer team may of course choose a different solution since I don't have the full picture of how it all works. Reproducible: Always Steps to Reproduce: (Example) 1. emerge fftw:3.0 # only the most recently built version will be installed 2. layman -a science 3. emerge =sci-chemistry/ambertools-12 # pkg-config fftw3 --libs fails due to the bug in p.1 or 1. emerge pykde4 Actual Results: Build errors and/or only one of several versions of the software/libraries (e.g., single precision instead of single and double precision) is installed which causes build failures of programs that depend on this package. Expected Results: Successful builds of these and dependent packages. emerge --info Portage 2.1.11.31 (default/linux/amd64/10.0/desktop/kde, gcc-4.6.3, glibc-2.15-r3, 3.5.7-gentoo x86_64)

I don't know who assigned the bug like this but the eclasses should be already fixed for a few days now, and the remaining ebuilds (which were too hacky to work) were fixed.
The bug in eclasses themselves was fixed faster than it was assigned. I noticed that currently the affected ebuilds I know of work fine. If the variable names were not fixed by now, a warning is issued while emerging the package. I understand that the support for the old-style variables is temporary and will be removed when all affected ebuilds in the official portage tree are adjusted to the new order. But your plans may be different. If you are convinced this bug should be marked as fixed, please close it.
Ok then. The compatibility code will be retained for a longer while as it does not hurt. Overlays should catch up as well.
