After using /usr/bin/cpan to update many modules, I've gotten versions confused:

$ perldoc perldoc
Encode object version 2.42_01 does not match bootstrap parameter 2.51 
+at /usr/lib/perl/5.14/DynaLoader.pm line 207.
Compilation failed in require at /usr/share/perl/5.14/Pod/Man.pm line 
+34.
BEGIN failed--compilation aborted at /usr/share/perl/5.14/Pod/Man.pm l
+ine 34.
Compilation failed in require at /usr/bin/pod2man line 19.
BEGIN failed--compilation aborted at /usr/bin/pod2man line 19.
Got a 0-length file from /usr/share/perl/5.14/pod/perldoc.pod via Pod:
+:Perldoc::ToMan!?

Where should I start looking?

In reply to I broke my system with cpan by Anonymous Monk
