| Subject: | Makefile.PL uses YAML::Tiny before CPAN can install it |
Makefile.PL calls WriteMyMeta which invokes YAML::Tiny before CPAN has
the opportunity to install the prerequisite. Perhaps Module::Install
cannot bootstrap itself.
Steps to repro:
Don't have YAML::Tiny
$ /opt/perl-5.10.1/bin/perl -d Makefile.PL
