Bugzilla Bug 58614

Emerge of eXtace fails during 'configure' stage citing a need for the fftw
libraries. Libraries for fftw are installed and were rebuilt just to be extra
sure.

Reproducible: Always
Steps to Reproduce:
1. emerge fftw extace
2.
3.

Actual Results:  
>>> Regenerating /etc/ld.so.cache...
 * Caching service dependencies...
>>> dev-libs/fftw-3.0.1 merged.
>>> Recording dev-libs/fftw in "world" favorites file...

>>> clean: No packages selected for removal.

>>> emerge (2 of 2) media-sound/extace-1.8.11 to /
>>> md5 src_uri ;-) extace-1.8.11.tar.gz
>>> Unpacking source...
>>> Unpacking extace-1.8.11.tar.gz to /var/tmp/portage/extace-1.8.11/work
>>> Source unpacked.

!!! FFTW libraries NOT found. eXtace will NOT compile without them!!!

Please install the FFTW library (Fastest FFT in the West), it is available from
http://www.fftw.org or from your most convienient .RPM .DEB or Gentoo mirror

 - Gentoo users can get it via "emerge fftw" as root
 - Debian users can get it via "apt-get fftw" or "apt-get fftw-lib" as root
 - RPM users (mandrake, suse, redhat) can install it via "urpmi fftw" or "urpmi
fftw-lib", or via http://RPMfind.net as root


!!! ERROR: media-sound/extace-1.8.11 failed.
!!! Function econf, Line 362, Exitcode 1
!!! econf failed


Expected Results:  
Well, I wouldn't expect that eXtace would miss a library that had been
installed
just for it, seconds before.

The -l flags indicate that iw was looking for librfftw and libdrfftw, which
aren't installed on this machine (libfftw3 is installed, as are libfftw3f,
libfftw3_threads, and libfftw3f_threads). I'm not sure what [r]/[dr]fftw are.

can you please:

emerge -v '\=dev-libs/fftw-2*'

I bet it needs the older fftw version...

fixed in portage.
