Imagemagick and jp2: no decode delegate

Processing jp2 images with imagemagick (which used to work for me, but I use it infrequently and so can't be sure when the change occurred) now produces an error:

convert: no decode delegate for this image format `t156.jp2' @ error/constitute.c/ReadImage/555.
convert: no images defined `t156.png' @ error/convert.c/ConvertImageCommand/3147

My delegates line from convert:

DELEGATES      bzlib mpeg fontconfig freetype gslib jng jpeg lcms lqr lzma openexr pango png ps rsvg tiff webp wmf x xml zlib

I have jasper 1.900.1-10 and openjpeg 1.5.1-2 installed; I tried also with openjpeg 2.0.0 installed from source and reinstalling imagemagick, but still no jp2 in the delegates line. 

Any ideas what I'm doing wrong?
