Sorry, just changing the builddeps as I suggested to remove armel gnat dep is not enough. It needs a clause in debian/rules too and control.in too. The f95 test fails:
Testing front-end f95 ./test_f95.sh: line 55: 30317 Segmentation fault $f95dir/x${index}f -dev $device -o ${OUTPUT_DIR}/x${index}f95.$dsuffix $options 2>test.error -- Process completed ***Failed but the package builds ok. Patches are attached. (cc-ing Colin Tuckley, our armel fortran wizard)
