+Perl can be built with extra modules or bundles of modules which
+will be fetched from the CPAN and installed alongside Perl.
-If you do not wish to put everything under a single prefix, that's
-ok. You will be prompted for the individual locations; this siteprefix
-is only used to suggest the defaults.
+Notice that you will need access to the CPAN; either via the Internet,
+or a local copy, for example a CD-ROM or a local CPAN mirror. (You will
+be asked later to configure the CPAN.pm module which will in turn do
+the installation of the rest of the extra modules or bundles.)
-The default should be fine for most people.
+Notice also that if the modules require any external software such as
+libraries and headers (the libz library and the zlib.h header for the
+Compress::Zlib module, for example) you MUST have any such software
+already installed, this configuration process will NOT install such
+things for you.
+If this doesn't make any sense to you, just accept the default '$dflt'.
