-* Known Problems
+If you want to use Perl on the Hurd, I recommend using the Debian
+GNU/Hurd distribution (see http://www.debian.org), even if an
+official, stable release has not yet been made. The old `gnu-0.2'
+binary distribution will most certainly have additional problems.
-There are several problems with Perl on the Hurd. Most of them are
-related to bugs in the OS, some might be actual bugs in Perl.
+* Known Problems
-The database code has problems that make Perl crash. When running the
-test-suite one of the tests will crash. Note that on the Hurd when a
-program crashes, the crash server suspends the program. Continuing
-the program will cause it to exit.
+The Perl testsuite may still report some errors on the Hurd. The
+`lib/anydbm.t' and `op/stat.t' tests will most certainly fail. The
+first fails because Berkeley DB 2 does not allow empty keys and the
+test tries to use them anyway. This is not really a Hurd bug. The
+same test fails on Linux with version 2.1 of the GNU C Library. The
+second failure is caused by a bug in the Hurd's filesystem servers,
+that we have not been able to fix yet. I don't think it is crucial.
The socket tests may fail if the network is not configured. You have
to make `/hurd/pfinet' the translator for `/servers/socket/2', giving
it the right arguments. Try `/hurd/pfinet --help' for more
-information. It seems that it is currently not possible to do this
-right when you do not have a supported network device. Therefore all
-tests that use INET sockets fail on my system, suggesting that the
-`localhost' address may not be defined.
+information.
Here are the statistics for Perl 5.005_03 on my system:

5 tests skipped, plus 14 subtests skipped.
-Failed 10/188 test scripts, 94.68% okay. 121/6467 subtests failed, 98.13% okay.
+Failed 2/189 test scripts, 98.94% okay. 2/6669 subtests failed, 99.97% okay.
+
+There are quite a few systems out there that do worse!
+
+However, since I am running a very recent Hurd snapshot, in which a lot of
+bugs that were exposed by the Perl testsuite have been fixed, you may
+encounter more failures. Likely candidates are: `lib/io_pipe.t',
+`lib/io_sock.t', `lib/io_udp.t' and `lib/time.t'.
