Setting Camera Response to linear has no effect on the pto file.  I'm not
sure that's related to the problem.  Here's what hugin is trying to do (from
the make file):

nona  -r hdr -m EXR_m -o test_hdr_ -i 0 test.pto
hugin_hdrmerge -m avg -c -o test_stack_hdr_0000.exr test_hdr_0000.exr
nona  -r hdr -m EXR_m -o test_hdr_ -i 1 test.pto
hugin_hdrmerge -m avg -c -o test_stack_hdr_0001.exr test_hdr_0001.exr
nona  -r hdr -m EXR_m -o test_hdr_ -i 2 test.pto
hugin_hdrmerge -m avg -c -o test_stack_hdr_0002.exr test_hdr_0002.exr
enblend  -w -f8000x4000 -o test_hdr.exr test_stack_hdr_0000.exr
test_stack_hdr_0001.exr test_stack_hdr_0002.exr

There's a warning from hugin_hdrmerge about "only one input image" but
again, I'm not sure if that's related.  The important point is that if you
look at the output .exr from this:

nona  -r hdr -m EXR_m -o test_hdr_ -i 0 test.pto

It is not hdr.  There's also a .pgm file produced but it doesn't seem to be
used by anything.
