Message ID:
That's actually "correct" for running "perl Build.PL" since "success" means
writing a Build file and metadata for CPAN/CPANPLUS to resolve
prerequisites. Having Build.PL (or Makefile.PL) announce missing
requirements is just a legacy behavior.

It's possible they should be quiet if they detect any of the "CPAN/CPANPLUS
is running" environment variables, but stock 5.8.4 wouldn't have them

And the meaning of "requires" is loose. Things *may* pass if they are not
satisfied, but authors don't promise anything. :-)

Unless something pops up on...
I tested on OpenSolaris/x86, which ships with perl-5.8.4 as the default
system perl.

I noted one odd thing:

$ perl Build.PL
Checking prerequisites...
   !  ExtUtils::CBuilder is not installed
   !  ExtUtils::ParseXS is not installed
   !  File::Temp (0.14) is installed, but we need version >= 0.15
   !  Test::Harness (2.40) is installed, but we need version >= 3.16
   !  Test::More (0.47) is installed, but we need version >= 0.49
   *  ExtUtils::Manifest (1.42) is installed, but we prefer to have 1.54
 [ . . . ]

ERRORS/WARNINGS FOUND IN PREREQUISITES. You may wish to install the versions
of the modules indica...
$ echo $?

Note that although the textual output complains about missing
prerequisites, the script exits with a 0 status.  The "requires" things
don't seem to really be required.  It still "passes" all its tests,
though it does skip quite a few.

$ ./Build test
[ . . . ]

All tests successful, 6 tests and 34 subtests skipped.
Files=44, Tests=1121, 78 wallclock secs (37.18 cusr + 18.89 csys = 56.07

In short, even though I'm missing several "required" prerequisites,

       perl Build.PL && ./Build && ./Build test && ./Build install

will happily build and install, and any warnings will have scrolled
hopelessly off screen.  I would have expected to have to give some sort of
--force flag to make it proceed anyway.
