noX11 doesn't affect loading of images, so it seems that the problem is
elsewhere. If indeed Prima was compiled with libjpeg ( what does
perl -MPrima -e 'print map { $_->{name}.qq(\n) } @{Prima::Image->codecs};'
say?) then there must be a problem with either zz.jpg or libjpeg itself.

The only cause I can immediateliy think of is that Prima detects if a
file to be loaded is indeed a jpeg file, by verifying its signature ( see
img/codec_jpeg.c , open_load() for more ), and (I'm just speculating) that
you have a file with a newer signature. I don't know if newer jpeg
signatures exists, but this happened once when Prima didn't know about
jpeg2000. You can try to stuff some debug printf's in there to be certain,
and you can also send this jpeg to me.
