=head2 FreeBSD 4.5 fails lib/File/Spec/t/rel2abs2rel.t
-Test 1 of F<lib/File/Spec/t/rel2abs2rel.t> runs "$^X" with a perl 1 liner.
+F<lib/File/Spec/t/rel2abs2rel.t> tests that "`` works" by running a
+a perl 1 liner in backticks, using "$^X" as the path to perl.
It is failing on FreeBSD 4.5, but only when run as part of make test.
This seems to be a kernel problem rather than perl - reading the symlink
F</proc/curproc/file> returns "unknown" rather than the path to perl, and a
kernel debugger reveals that variable C<numfullpathfail2> in
-F</usr/src/sys/miscfs/procfs/procfs_vnops.c> is being incremented whenever
+F</usr/src/sys/kern/vfs_cache.c> is being incremented whenever
F</proc/curproc/file> fails to return the perl executable's path.
