I can duplicate your problem on perl 5.14.2 and Pod::Perldoc 3.15_04. Try to use the later version, as daxim suggested. If that doesn't work, try to debug using PERLDOCDEBUG.

From perl5160delta:

Pod::Perldoc has been upgraded from version 3.15_03 to 3.17. ... This upgrade has numerous significant fixes. Consult its changelog on the CPAN for more information.
