AFAICT (the size of the attachment posed difficulties), your 'perlbrew' installation successfully built Perl 5.14.0, but some tests failed during 'make test'. Generally the failures looked like this: ### String found where operator expected at /admin/perl5/perlbrew/build/perl-5.14.0/cpan/ExtUtils-Constant/../../lib/Carp.pm line 145, near "$arg =~ s/'/\\'" (Missing operator before '/\\'?) Global symbol "$where" requires explicit package name at /admin/perl5/perlbrew/build/perl-5.14.0/cpan/ExtUtils-Constant/../../lib/Carp.pm line 118. Global symbol "$arg" requires explicit package name at /admin/perl5/perlbrew/build/perl-5.14.0/cpan/ExtUtils-Constant/../../lib/Carp.pm line 118. Global symbol "$arg" requires explicit package name at /admin/perl5/perlbrew/build/perl-5.14.0/cpan/ExtUtils-Constant/../../lib/Carp.pm line 118. ### In other words, the problems occurred in lib/Carp.pm when called from tests of 'dual-life' modules. Apart from using perlbrew, are you able to build and test Perl 5.14 successfully on this machine? Thank you very much. Jim Keenan
