[Module-build-general] Module::Info

[Dominic M. <do...@se...>]

I've just found an interesting problem.  If you don't already have a 
module installed, then Module::Info can fail when you do "make dist".

For example, I've just found that I don't have Test::XML on my 
workstation.  This shouldn't be a problem, but when I tried to do "make 
dist", I got this error message:

Scanning lib/Test/XML/SAX.pm for packages
B::Module::Info,packages use failed with 2 saying:
Can't locate Test/XML.pm in @INC (@INC contains: /home/dom/libexec/perl

/home/dom/work/Test-XML/lib/Test/XML/SAX.pm line 9.

Test::XML::SAX is a module that depends upon Test::XML, both of which 
are included in my distribution.

I would guess that to fix this, you probably need to include blib/lib 
and blib/arch in @INC somehow.  However, this would mean that you need 
to run a build before you make a dist.  I'm not entirely sure that this 
is the right answer, though...

Just to confirm, I can manually fix the problem by doing:

% perl Build
% env PERL5LIB="$PWD/blib/arch:$PWD/blib/lib" perl Build dist
