Emerging media-sound/rezound-0.9.0_beta gets the following in the configure operation: checking for fftw.h... no configure: WARNING: ***** fftw.h header file not found -- any FFT based actions will be disabled (http://www.fftw.org) ***** checking rfftw.h usability... no checking rfftw.h presence... no checking for rfftw.h... no configure: WARNING: ***** rfftw.h header file not found -- any FFT based actions will be disabled (http://www.fftw.org) ***** The ebuild specifies: >=dev-libs/fftw-2.1.5 Which will select dev-libs/fftw-3.0.1 and that version doesn't have either of the required header files. Emerging dev-libs/fftw-2.1.5 and rebuilding rezound works (fftw has different slots for the various versions). The rezound ebuild needs to have it's dependency on fftw changed or the upstream source needs to be changed to work with fftw-3.
Updated the depend on rezound to =dev-libs/fftw-2*
