perl5.002beta3
[editor's note: no patch file was found for this release, so no fine-grained changes] I can't find the password for our ftp server, so I had to drop it into ftp://ftp.sems.com/pub/incoming/perl5.002b3.tar.gz, which is a drop directory you can't ls. The current plan is that Andy is gonna whack on this a little more, and then release a gamma in a few days when he's happy with it. So don't get carried away. This is now *late* beta. In other words, have less than the appropriate amount of fun. :-) Larry

+# This is a hints file for DGUX, which is Data General's Unix. It was
+# developed using version 5.4.3.10 of the OS. I think the gross
+# features should work with versions 5.4.2 through 5.4.4.11 with perhaps
+# minor tweaking, but I don't have any older or newer versions installed
+# at the moment with which to test it.

+# DGUX is a SVR4 derivative. It ships with gcc as the standard
+# compiler. Since version 5.4.3.0 it has shipped with Perl 4.036
+# installed in /usr/bin, which is kind of neat. Be careful when you
+# install that you don't overwrite the system version, though (by
+# answering yes to the question about installing perl as /usr/bin/perl),
+# as it would suck to try to get support if the vendor learned that you
+# were physically replacing the system binaries.
#
+# Be aware that if you opt to use dynamic loading you'll need to set
+# your $LD_LIBRARY_PATH to include the source directory when you build,
+# test and install the software.
