ImageMagick is much easier:

magick convert -dispose previous -delay 10 +repage FRAMES/*.gif -loop 0 
NEW.gif

I've found that converting each frame to a GIF prior to running the 
above results in a smaller result.

I have also used ffmpeg to make a MP4 movie from individual images:

Create a file "durations.txt". Ex.
  file frame1.gif
  duration 1
  file frame2.gif
  duration 1
    :
  file frame(N-1).gif

The last image does not have a "duration 1" line.

Then

  # Windows cannot do globbing for input images
  # -pix_fmt yuv420p required for quicktime & windows media player
  # -fps=10 required for vlc media player which cannot deal with a
  # lower fps
  ffmpeg -f concat -i durations.txt -framerate 1 -vsync vfr -c:v \
    libx264 -preset slow -crf 22 -an -vf fps=10 -pix_fmt yuv420p \
    -y MOVIE.mp4

I've done this on windows but these tools are available for unix too. 
ImageMagick was developed for unix. You can easily find documentation 
and examples via a quick google.
