It seems that GDAL_SKIP="JPEG2000,JP2OpenJPEG" is not working for gdal 1.11 I 
should use ' ' rather than ",".

Do you know any build issue on trunk or 1.10? I can't build this release from 
git repository.

Do you know any limitation on jp2OpenJpeg? I get a segmentation fault with 
this driver:

Here is the bt (from gdal 1.11, but get almost the same from trunk, line 
number is different):
