| Subject: | Module::Build install path can be taken when Module::Build is not installed |
I apologise if I don't have conclusive proof for this, but reading
through the CPAN.pm code the following would appear to be true.
IF a distribution has only Build.PL
AND Module::Build is not installed on host
THEN CPAN.pm will select the Build.PL install method
RESULTING IN the installer crashing due to lack of Module::Build.
This is despite CPAN being able to _know_ that M:B isn't installed and
that in all certainty perl Build.PL is going to crash.
This results in confusing and misleading errors to the user when CPAN
could just make sure that M:B is installed before calling Build.PL.
On the plus side it does appear that if a module has BOTH installers and
M:B is not installed CPAN.pm picks Makefile.PL regardless.
Solutions:
----------
1. Add Module::Build as a compulsory dependency for CPAN itself.
(Does M:B work everywhere? It's certainly heading for core)
2. Automatically install Module::Build if it encounters a Build.PL-only
distribution. (prefered maybe?)
Hard to know what to do, but I'm expecting to start seeing errors soon.
