First, make sure you are installing an up-to-date version of Perl. If
you didn't get your Perl source from CPAN, check the latest version at
-<URL:http://www.perl.com/CPAN/src/>.
+<URL:http://www.cpan.org/src/>.
The basic steps to build and install perl5 on a Unix system
with all the defaults are:
=head1 WARNING: This version requires a compiler that supports ANSI C.
-If you find that your C compiler is not ANSI-capable, try obtaining
-GCC, available from GNU mirrors worldwide (e.g. ftp://ftp.gnu.org/pub/gnu).
+Most C compilers are now ANSI-compliant. However, a few current
+computers are delivered with an older C compiler expressly for
+rebuilding the system kernel, or for some other historical reason.
+Alternatively, you may have an old machine which was shipped before
+ANSI compliance became widespread. Such compilers are not suitable
+for building Perl.
+
+If you find that your default C compiler is not ANSI-capable, but you
+know that an ANSI-capable compiler is installed on your system, you
+can tell F<Configure> to use the correct compiler by means of the
+C<-Dcc=> command-line option -- see L<"gcc">.

+If do not have an ANSI-capable compiler there are several avenues open

+You may try obtaining GCC, available from GNU mirrors worldwide,
+listed at <URL:http://www.gnu.org/order/ftp.html>. If, rather than
+building gcc from source code, you locate a binary version configured
+for your platform, be sure that it is compiled for the version of the
+operating system that you are using.

+
+You may purchase a commercial ANSI C compiler from your system
+supplier or elsewhere. (Or your organization may already have
+licensed such software -- ask your colleagues to find out how to
+access it.) If there is a README file for your system in the Perl
+distribution (for example, F<README.hpux>), it may contain advice on
+suitable compilers.

Another alternative may be to use a tool like ansi2knr to convert the
sources back to K&R style, but there is no guarantee this route will get
you anywhere, since the prototypes are not the only ANSI features used
form, be sure to email perlbug@perl.com to let us know the steps you
followed. This will enable us to officially support this option.

Although Perl can be compiled using a C++ compiler, the Configure script
does not work with some C++ compilers.
As a final catch-all, Configure also offers an $otherlibdirs
variable. This variable contains a colon-separated list of additional
-directories to add to @INC. By default, it will be set to
-$prefix/site_perl if Configure detects that you have 5.004-era modules
-installed there. However, you can set it to anything you like.
+directories to add to @INC. By default, it will be empty.
+Perl will search these directories (including architecture and
+version-specific subdirectories) for add-on modules and extensions.

+The F<Configure> program has not been able to find all the files which
+make up the complete Perl distribution. You may have a damaged source
+archive file (in which case you may also have seen messages such as
+C<gzip: stdin: unexpected end of file> and C<tar: Unexpected EOF on
+archive file>), or you may have obtained a structurally-sound but
+incomplete archive. In either case, try downloading again from the
+official site named at the start of this document. If you do find
+that any site is carrying a corrupted or incomplete source code
+archive, please report it to the site's maintainer.
+
+This message can also be a symptom of using (say) a GNU tar compiled
+for SunOS4 on Solaris. When you run SunOS4 binaries on Solaris the
+run-time system magically alters pathnames matching m#lib/locale# - so
+when tar tries to create lib/locale.pm a differently-named file gets
+created instead.
+
+You may find the file under its assumed name and be able to rename it
+back. Or use Sun's tar to do the extract.
