looks more like /usr/lib64/libraw_r.so is broken. what package provides that on your system ?
This looks like openmp is enabled in libraw and disabled for the build of luminance_hdr. The problem occurs since we conditionally enable openmp for luminance_hdr and the build system doesn't use pkg-config to check if libraw requires it. This should be fixed in luminance_hdr-2.2.0 that moved to a cmake build system so I'm going to close this bug as fixed and put the stabilizing bug on hold until 2.2.0 has been in the tree for 30 days.
