I am working on getting a local installation of CPAN working, and in most cases following the instructions here have worked perfectly.

However, some module installations have tests with the -T flag. Test::Pod is an example. Even though my local installation paths are set in the $PERL5LIB environment variable, I am getting failures on the tests due to "module not found in @INC" and the displayed @INC does not contain the paths specified in $PERL5LIB. Normal taint behavior (according to perlsec) ignores this env var, but documentation for test_harness says it will load them into @INC for those in my scenario. I also tried adding -I and -Mlib= arguments to the FULLPERL definition in the makepl_arg argument in the ~/.cpan/CPAN/MyConfig.pm to no avail, regardless of the quoting methods I used. Only if I typo the path to not be those in $PERL5LIB will they show up in the @INC error message on the test failure.

How should one work around tests with the taint flag with local installations via CPAN? Modifying the test files themselves to remove the -T argument, or to add in 'use lib ="~/lib/perl5";' seems to be a very inelegant solution.
