[Module::Build] MBC possible missing dependency

[Jim C. <jc...@di...>]

MBers,

it appears that  Module::Build::Compat  'make test' skips 'make'
in some circumstances.


1. make clean, make  is OK - lib -> blib happens

[jimc@harpo Array-Compare-1.09]$ make clean
/usr/local/bin/perl Build clean
Deleting blib
[jimc@harpo Array-Compare-1.09]$ make
/usr/local/bin/perl Build
lib/Array/Compare.pm -> blib/lib/Array/Compare.pm
Manifying blib/lib/Array/Compare.pm -> blib/libdoc/Array::Compare.3

2. make clean, make test - OK - lib -> blib happens

[jimc@harpo Array-Compare-1.09]$ make clean
/usr/local/bin/perl Build clean
Deleting blib
[jimc@harpo Array-Compare-1.09]$ make test
/usr/local/bin/perl Build test
lib/Array/Compare.pm -> blib/lib/Array/Compare.pm
t/pod.....make: *** [test] Interrupt

3. perl Makefile.PL, make test NOT OK  lib -> blib SKIPPED

[jimc@harpo Array-Compare-1.09]$ perl Makefile.PL
/usr/local/bin/perl Build.PL
Checking whether your kit is complete...
Looks good
Deleting Build
Removed previous script 'Build'
Creating new 'Build' script for 'Array-Compare' version '1.09'
[jimc@harpo Array-Compare-1.09]$ make test
/usr/local/bin/perl Build test
t/pod.....make: *** [test] Interrupt

4. make clean, perl Makefile.PL, make test OK -

[jimc@harpo Array-Compare-1.09]$ make clean
/usr/local/bin/perl Build clean
Deleting blib
[jimc@harpo Array-Compare-1.09]$ perl Makefile.PL
/usr/local/bin/perl Build.PL
Checking whether your kit is complete...
Looks good
Deleting Build
Removed previous script 'Build'
Creating new 'Build' script for 'Array-Compare' version '1.09'
[jimc@harpo Array-Compare-1.09]$ make test
/usr/local/bin/perl Build test
lib/Array/Compare.pm -> blib/lib/Array/Compare.pm
t/pod.....


from 3,4 I infer that  perl Makefile.PL doesnt automatically invalidate blib
by Makefile being newer than blib.

while that might be a feature (of really knowing nothing changed), it 
could also
be a mising dependency.

5. I change Makefile inside by giving it a new prefix.
no lib->blib rebuild.
This still might be ok, IFF MB is really smart, and knows that a diffferent
install location doesnt need a re-make.

[jimc@harpo Array-Compare-1.09]$ perl Makefile.PL PREFIX=~
/usr/local/bin/perl Build.PL config=prefix=/home/jimc
Checking whether your kit is complete...
Looks good
Deleting Build
Removed previous script 'Build'
Creating new 'Build' script for 'Array-Compare' version '1.09'
[jimc@harpo Array-Compare-1.09]$ make
/usr/local/bin/perl Build
[jimc@harpo Array-Compare-1.09]$

6. same as above, but with perl Makefile.PL distdir=~


This could be an " Ouch!,  Well - dont do that " problem,
but I thought it worth flagging.

tia,
