I am looking for an LTO tape library. Do you have one to spare?

FFTW is a C subroutine library for computing the Discrete Fourier Transform
(DFT) in one or more dimensions, of both real and complex data, and of
arbitrary input size. We believe that FFTW, which is free software, should
become the FFT library of choice for most applications. Our benchmarks,
performed on a variety of platforms, show that FFTW's performance is
typically superior to that of other publicly available FFT software.
Moreover, FFTW's performance is portable: the program will perform well on
most architectures without modification.

The FFTW package was developed at MIT by Matteo Frigo and Steven G.
Johnson.  Please send email to fftw@theory.lcs.mit.edu so that we can keep
track of users and send you information about new releases.  The latest 
version of FFTW, benchmarks, links, and other information can be found at
the FFTW home page.

for Libraries * - deleted ports are only shown under the This port is required by section. It was harder to do for the Required section. Perhaps later...

To install the port: cd /usr/ports/math/fftw3-float/ && make install clean
To add the package: pkg install math/fftw3-float


Configuration Options
===> The following configuration options are available for fftw3-float-3.3.3_1:
     G77_WRAPPERS=off: Alter Fortran wrappers for use with g77
     OPENMP=off: Build OpenMP multithreaded libraries
     OPTIMIZED_CFLAGS=on: Use extra compiler optimizations
===> Use 'make config' to modify these settings

    Affects: users of math/fftw3 math/fftw3-long math/fftw3-float
    Author: db@FreeBSD.org
    Reason: 
      The Fortran option has removed from fftw3 and moved into slave ports,
      math/fftw3-fortran math/fftw3-long-fortran and math/fftw3-float-fortran.

- After digging into the Makefile and configure for fftw3 I discovered
  that USE_FORTRAN was only used to determine what name mangling scheme
  it had to use to compile the shim libs for fortran, but compiling everything
  using 'C' anyway.
  With this diff, the slave ports fftw3-long-fortran, fftw3-float-fortran
  and fftw3-fortran disapear since the shims are always built, without
  necessitating the use of a USE_FORTRAN.

- Ensure Fortran shim is not built if USE_FORTRAN is not set.
- Split Fortran option into slave ports fftw3-fortran long-fortran float-fortran
- Have to bump PORTREVISION for package builds etc..
- Fix silly spelling mistakes "Percision" -> "Precision" noted.
