This is a bug report for perl from dom@earth.li,
generated with the help of perlbug 1.39 running under perl 5.18.0.


-----------------------------------------------------------------
perldoc used to spit out the raw POD if no nroffer was available,
but now it fails altogether:

| $ perldoc perldoc
| Use of uninitialized value $roffer in concatenation (.) or string at /usr/share/perl/5.18/Pod/Perldoc/ToMan.pm line 53.
| Use of uninitialized value in concatenation (.) or string at /usr/share/perl/5.18/Pod/Perldoc/ToMan.pm line 303.
| Use of uninitialized value in pattern match (m//) at /usr/share/perl/5.18/Pod/Perldoc/ToMan.pm line 308.
| Error while formatting with Pod::Perldoc::ToMan:
|  no nroffer!?
|  at /usr/share/perl/5.18/Pod/Perldoc.pm line 1346.
|
|
|  at /usr/bin/perldoc line 10.
| Got a 0-length file from /usr/share/perl/5.18/pod/perldoc.pod via Pod::Perldoc::ToMan!?
|
|  at /usr/bin/perldoc line 10.

Ideally, it should fall back to Pod::Text (aka perldoc -t), which is
always available and doesn't rely on any external formatter.
