Prepending blib/arch and blib/lib of 108 build dirs to PERL5LIB; for 'get'
"cpan -t . " works in the same way and if the tests fail then "cpan ." stops there - so I cannot tell if it would install the dependencies in the case when the tests pass.
I don't really know how to investigate it further - but I am noting that as it is very frustrating. Eventually I had to resort to cpanminus ("cpanm --installdeps ." is really handy as it addresses the problem directly).
