I started trying it and hit something really weird... or maybe I've just 
been working too many days in a row.

Why this difference depending on whether I reference a module with an 
absolute path or a relative one?

[peter@tweety ~]$ /usr/bin/perl -wc /usr/lib/perl5/5.6.0/Shell.pm
/usr/lib/perl5/5.6.0/Shell.pm syntax OK

[peter@tweety ~]$ cd /usr/lib/perl5/5.6.0/

[peter@tweety 5.6.0]$ /usr/bin/perl -wc /usr/lib/perl5/5.6.0/Shell.pm
/usr/lib/perl5/5.6.0/Shell.pm syntax OK

[peter@tweety 5.6.0]$ /usr/bin/perl -wc Shell.pm
Name "Shell::capture_stderr" used only once: possible typo at Shell.pm line 3.
Shell.pm syntax OK

[peter@tweety 5.6.0]$ cd ..

[peter@tweety perl5]$ /usr/bin/perl -wc 5.6.0/Shell.pm
Name "Shell::capture_stderr" used only once: possible typo at 
5.6.0/Shell.pm line 3.
5.6.0/Shell.pm syntax OK

Nothing up my sleeve:

[peter@tweety perl5]$ env | grep -i perl
PWD=/usr/lib/perl5
[peter@tweety perl5]$

Color me baffled.  And it's not just that module, there are many that 
exhibit this behavior, so it's something to do with perl -cw.
