It can be used after running:\n\nmake install\n\n(or your platform's equivalent procedure) to verify that perl and its libraries have been\ninstalled correctly.  A correct installation is verified by output that looks like:\n\nok 1\nok 2\n\netc.\n",

Correct by conducting\na proper installation.\n\n•   print \"# Perl version '$]' installed, expected $ivpVERSION.\\n\";\n\nLikely to occur for a perl that was not properly installed.  Correct by conducting a\nproper installation.\n\n•   print \"# Perl \\@INC directory '$' does not appear to exist.\\n\";\n\nLikely to occur for a perl library tree that was not properly installed.  Correct by\nconducting a proper installation.\n\n•   print \"# Needed module '$' does not appear to be properly installed.\\n\";\n\nOne of the two modules that is used by perlivp was not present in the installation.  This\nis a serious error since it adversely affects perlivp's ability to function.  You may be\nable to correct this by performing a proper perl installation.\n\n•   print \"# Required module '$' does not appear to be properly installed.\\n\";\n\nAn attempt to \"eval \"require $module\"\" failed, even though the list of extensions\nindicated that it should succeed.  Correct by conducting a proper installation.\n\n•   print \"# Unnecessary module 'bLuRfle' appears to be installed.\\n\";\n\nThis test not coming out ok could indicate that you have in fact installed a bLuRfle.pm\nmodule or that the \"eval \" require \\\"$modulename.pm\\\"; \"\" test may give misleading\nresults with your installation of perl.  If yours is the latter case then please let the\nauthor know.\n\n•   print \"# file\",+($#missing == 0) ? '' : 's',\" missing from installation:\\n\";\n\nOne or more files turned up missing according to a run of \"ExtUtils::Installed ->\nvalidate()\" over your installation.  Correct by conducting a proper installation.\n\nFor further information on how to conduct a proper installation consult the INSTALL file that\ncomes with the perl source and the README file for your platform.\n",
