After not reaching the package maintainer (takashina at computer.org) I hope someone on R-help@ can help. I tried to install rimage_0.5-7.tar.gz under FreeBSD-7.0 CURRENT as root with the following command: R CMD INSTALL rimage_0.5-7.tar.gz It stops with the following errors in the configure script: [...snip...] checking fftw.h usability... no checking fftw.h presence... no checking for fftw.h... no [...snip...] On my system this header file is located under /usr/local/include/fftw.h Different FreeBSD packages need different versions of fftw, so I have three versions installed: fftw-2.1.5_4 fftw3-3.1.2 fftw3-float-3.1.2 Is it possible that this is the reason for not finding the header? The installation works well, when giving configure-args with the paths: R CMD INSTALL --configure-args="--with-fftw-include=/usr/local/include/ --with-jpeg-include=/usr/local/include/" rimage_0.5-7.tar.gz Anyone else having this problem on FreeBSD? Many thanks in advance, Rainer Hurling
