math/fftw3 missing header file

[Alex Kloss]

Hello all,

I installed math/fftw3 today because a program I'm working on porting
to FreeBSD  (http://arss.sourceforge.net/) requires it. However, when
I ran make, it gave me the following error:

Scanning dependencies of target arss
[ 20%] Building C object CMakeFiles/arss.dir/arss.o
/home/alex/Desktop/arss-0.2.3-src/src/arss.c:22:19: error: fftw3.h: No
such file or directory
*** Error code 1

Stop in /usr/home/alex/Desktop/arss-0.2.3-src/src.

*** Error code 1

Stop in /usr/home/alex/Desktop/arss-0.2.3-src/src.

The pkg-plist for math/fftw3 says that it installs "fftw3.h," but I
could not find this file anywhere in my system using the find command.

Any thoughts?

Thanks,
