Hi Jim,

The issue I observed before is weird.

Now  make check passed against the following combination:
1. Refresh installed host in Ubuntu10.0.4, 
filefrag comes from E2fsprogs 1.41.11 && Kernel: 2.6.32-16
2. filefrag in e2fsprogs-1.4.12 && kernel-2.6.36.

$ sudo make check TESTS=cp/sparse-fiemap VERBOSE=yes
[sudo] password for jeff: 
make  check-TESTS
make[1]: Entering directory `/home/jeff/opensoure_dev/coreutils/tests'
make[2]: Entering directory `/home/jeff/opensoure_dev/coreutils/tests'
PASS: cp/sparse-fiemap
=============
1 test passed
=============
make[2]: Leaving directory `/home/jeff/opensoure_dev/coreutils/tests'
make[1]: Leaving directory `/home/jeff/opensoure_dev/coreutils/tests'


Thanks,
-Jeff
