[gmx-users] Density of States syntax question

Per your suggestion, I uninstalled Gromacs v5.1.2, and installed Gromacs v5.0.1, and re-ran the tutorial (changing from TIP4PEW to TIP4P for simplicity). The tutorial ran fine, but when I tried calculating the dos, I get the following error message:
Program gmx, VERSION 5.0.1
Source code file: /home/chaps/Work/gromacs/gromacs-5.0.1/src/gromacs/fft/fft_fftw3.cpp, line: 309
Error initializing FFTW3 plan.
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
I didn't notice any errors regarding fftw3 when I was installing this version of Gromacs (I followed the 'quick and dirty installation' from http://www.gromacs.org/Documentation/Installation_Instructions_5.0). I didn't think I needed any pre-requisite libraries, as I thought gromacs would install any necessary fftw libraries. Is this assumption wrong, or is there something else wrong here?

That's an bug that was not corrected yet for the 5.1 version. Its somehow linked to a safety measure that went nuts. The issue was already directed to the admins.
Try to use 501 version. For me, it works just fine.
