With the new gem2deb (not uploaded yet), yes. gem2deb will prepare the
$LOAD_PATH automatically to run the tests against the code that was
installed in debian/$package so the maintainer does not need to manually
manipulate the $LOAD_PATH.

The problem is that gem2deb builds the C extension for 1.8 in ext/mri,
then cleans (as in `make clean`), and then builds for 1.9 in the same
directory. This all happens before the tests are run, so when you add
"ext/mri" to the $LOAD_PATH in the test file, it only contains a 1.9
.so, and that's why the 1.8 tests segfault.
