I was trying to build swh-plugins 0.42 from the tarball on Mandrake, but configure complained about a lack of fftw3f. Mandrake doesn't include up to date RPMs of fftw. I had to build fftw 3.0 from source using ./configure --enable-float then add an environment variable in bash: export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig Just thought other Mandrake users might like to know that... Cheers Daniel
