I've been attempting to build Scalar-List-Utils-1.17 with perl5.004, but
I've encountered a circular dependency in the modules that get used by the
build process
$ cd Scalar-List-Utils-1.17
$ perl5.004 Makefile.PL
Can't locate File/Spec.pm in @INC at inc/Module/Install/Can.pm -
/Users/gbarr/Library/Perl/Module/Install/Can.pm line 7.
BEGIN failed--compilation aborted at inc/Module/Install/Can.pm -
/Users/gbarr/Library/Perl/Module/Install/Can.pm line 7.

/Users/gbarr/Library/Perl/Module/Install/Makefile.pm line 95, near "}"
The 'can_cc' method does not exist in the 'inc' path!
Please remove the 'inc' directory and run Makefile.PL again to load it.
OK, so I next tried to build File-Spec-0.90
$ cd File-Spec-0.90
$ perl5.004 Build.PL
Can't locate Module/Build.pm in @INC at Build.PL line 1.
BEGIN failed--compilation aborted at Build.PL line 1.
Ok, so I now try Module-Build-0.2611
$ cd Module-Build-0.2611
$ perl5.004 Build.PL
Can't locate File/Spec.pm in @INC at Build.PL line 5.
BEGIN failed--compilation aborted at Build.PL line 5.
Ugh! Circular dependency between File-Spec and Module-Build.
Ahh, but both File-Spec and Module-Build ship with a Makefile.PL, so let's
try that route
$ cd ../Module-Build-0.2611
$ perl5.004 Makefile.PL
Can't locate File/Spec.pm in @INC at lib/Module/Build/Compat.pm line 7.
BEGIN failed--compilation aborted at lib/Module/Build/Compat.pm line 7.
BEGIN failed--compilation aborted at Makefile.PL line 6.
And now File-Spec
$ cd ../File-Spec-0.90
$ perl5.004 Makefile.PL
Warning: prerequisite Cwd 2.17_02 not found at (eval 1) line 221.
Warning: prerequisite Test 0 not found at (eval 1) line 221.
Warning: prerequisite Test::More 0 not found at (eval 1) line 221.
Writing Makefile for File::Spec
Hmm, no circular dependency anymore, but we have a few more dependencies.
Looking at the first, Cwd
$ cd Cwd-2.21
$ perl5.004 Build.PL
Can't locate Module/Build.pm in @INC at Build.PL line 1.
BEGIN failed--compilation aborted at Build.PL line 1.
Hmm, the dependency chain is Cwd -> Module::Build -> File::Spec -> Cwd
Try the Makefile.PL that ships with Cwd
$ cd Cwd-2.21
$ perl5.004 Makefile.PL
Warning: prerequisite File::Spec 0 not found at (eval 1) line 221.
Warning: prerequisite Scalar::Util 0 not found at (eval 1) line 221.
Warning: prerequisite Test::More 0 not found at (eval 1) line 221.
Warning: prerequisite XSLoader 0 not found at (eval 1) line 221.
Writing Makefile for Cwd
And we are back in circular dependency mode again. Cwd-> File::Spec -> Cwd
Is there any way out of this "maze of twisty little passages"?
