Looks like the test setup doesn't have the right @INC directory/ies.
The only thing the test does is attempt to 'use' the BackupPC::XS
module. Exactly two files are required for the test to be able to do
that. As you know, those files need to be somewhere in the list of
directories in the Perl @INC environment variable, which is helpfully
listed by the report. If you haven't yet run the install step to put
the modules somewhere in the /usr/ tree then the only place they will
be found in your test system is under (what seems to me to be) the
rather expansively named
/builddir/build/BUILD/BackupPC-XS-0.63rc1-build/backuppc-xs-0.63rc1/
What's beneath that directory?
The canonical build creates a directory called '.../blib/' in the
top-level directory of the source tree, and for tests puts the files
beneath that directory.
Sorry, I've no idea what a version modified by Red Hat will do. :/
An example from one of the systems here on which I've built 0.63rc1
using the source which is at present on Github:
$ ls -l backuppc-xs/blib/lib/BackupPC/XS.pm
-r--r--r-- 1 ged ged 7689 Nov 8 16:01 XS.pm
$ ls -l backuppc-xs/blib/arch/auto/BackupPC/XS/XS.so
-rwxr-xr-x 1 ged ged 548768 Nov 29 18:25 arch/auto/BackupPC/XS/XS.so
$
Assuming that you have the two files, to test the test you could put
them temporarily in appropriate places in your system directories so
that Perl will be able to find and load them. Then you'll know if the
problem is just finding the modules in @INC, or something more curious.
