Subject: CPAN::HandleConfig::home ignores "undef" return from File::HomeDir->my_data
CPAN::HandleConfig::home does not handle a return of "undef" from File::HomeDir->my_data. In my particular network configuration this arises, causing CPAN to incorrectly ignore my ~/.cpan/CPAN/MyConfig.pm and try to run CPAN::FirstTime::init. (I'm not sure why it does the latter, but that's not part of this bug report.) The details: CPAN is being invoked in a ssh session into an OS X box, which gets its user account information via NIS. My account is "foreign" (i.e. not created on the Mac) and File::HomeDir->my_data() returns "undef" (which seems appropriate). Unfortunately, this causes CPAN::HandleConfig::load to ignore my existing ~/.cpan/CPAN/MyConfig.pm (as the path to it is now wrong) and to try to create a new one. (It should be noted that CPAN::FirstTime::init uses a different algorithm to determine where the config file goes; it just uses $ENV{HOME}). The most obvious solution would be to check the return from File::HomeDir->my_data and if it is "undef" to fall back to using $ENV{HOME} or File::HomeDir->my_home.
