NAME
       perlivp - Perl Installation Verification Procedure

SYNOPSIS
       perlivp [-p] [-v] [-h]

DESCRIPTION
       The perlivp program is set up at Perl source code build time to test the Perl version it was built under.  It can be
       used after running:

	   make install

       (or your platform's equivalent procedure) to verify that perl and its libraries have been installed correctly.  A
       correct installation is verified by output that looks like:

	   ok 1
	   ok 2

       etc.

OPTIONS
       -h help
	    Prints out a brief help message.

       -p print preface
	    Gives a description of each test prior to performing it.

       -v verbose
	    Gives  more detailed information about each test, after it has been performed.  Note that any failed tests ought
	    to print out some extra information whether or not -v is thrown.

DIAGNOSTICS
       •   print "# Perl binary '$perlpath' does not appear executable.\n";

	   Likely to occur for a perl binary that was not properly installed.  Correct by conducting a proper installation.

       •   print "# Perl version '$]' installed, expected $ivp_VERSION.\n";

	   Likely to occur for a perl that was not properly installed.	Correct by conducting a proper installation.

       •   print "# Perl \@INC directory '$_' does not appear to exist.\n";

	   Likely to occur for a perl library tree that	 was  not  properly  installed.	  Correct  by  conducting  a  proper
	   installation.

       •   print "# Needed module '$_' does not appear to be properly installed.\n";

	   One	of  the	 two  modules  that is used by perlivp was not present in the installation.  This is a serious error
	   since it adversely affects perlivp's ability to function.  You may be able to correct this by performing a proper
	   perl installation.

       •   print "# Required module '$_' does not appear to be properly installed.\n";

	   An attempt to "eval "require $module"" failed, even though the  list	 of  extensions	 indicated  that  it  should
	   succeed.  Correct by conducting a proper installation.

       •   print "# Unnecessary module 'bLuRfle' appears to be installed.\n";

	   This	 test not coming out ok could indicate that you have in fact installed a bLuRfle.pm module or that the "eval
	   " require \"$module_name.pm\"; "" test may give misleading results with your installation of perl.  If  yours  is
	   the latter case then please let the author know.

       •   print "# file",+($#missing == 0) ? '' : 's'," missing from installation:\n";

	   One	or  more  files	 turned	 up  missing  according	 to  a	run of "ExtUtils::Installed -> validate()" over your
	   installation.  Correct by conducting a proper installation.

       For further information on how to conduct a proper installation consult the INSTALL file that  comes  with  the	perl
       source and the README file for your platform.
