It works for me too as long as I'm not building with a directory with
"blib" in its name. The smoker that failed at PathTools built its
@INC for miniperl like so:
$ perl -"Ilib" -e "require 'lib/buildcustomize.pl'; print join qq/\n/, @INC;"
SMOKE_BUILD_ROOT:[fake-pm_to_blib.cpan.AutoLoader.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.Carp.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.PathTools]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.PathTools.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.ExtUtils-Command.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.ExtUtils-Install.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.cpan.ExtUtils-MakeMaker.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.ExtUtils-Manifest.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.cpan.File-Path.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.ext.re]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.Term-ReadLine.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.Exporter.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.ext.File-Find.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.cpan.Text-Tabs.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.dist.constant.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib.ext.VMS-Filespec.lib]
SMOKE_BUILD_ROOT:[fake-pm_to_blib]lib
/perl_root/lib/site_perl/VMS_IA64
/perl_root/lib/site_perl
/perl_root/lib/VMS_IA64/5_16_1
/perl_root/lib
.
But the Makefile.PL for PathTools has this line at the top:
BEGIN { @INC = grep {!/blib/} @INC }
which wipes out all of the entries in @INC that have fake-pm_to_blib
in the name:
$ perl -"Ilib" -e "require 'lib/buildcustomize.pl'; @INC = grep
{!/blib/} @INC; print join qq/\n/, @INC;"
/perl_root/lib/site_perl/VMS_IA64
/perl_root/lib/site_perl
/perl_root/lib/VMS_IA64/5_16_1
/perl_root/lib
.
So that's probably a bug in PathTools that only got exercised because
my smokes make directory names based on branch names and you happened
to make a branch name with "blib" in it.
And now for the really good part: build time decreased by 39%.
