hmm did you notice that Can't locate Module.pm in @INC is not in perldiag?

The corresponding error is only called Can't locate %s

Which means searching for '@INC' wouldn't help...

Though you're right about the full message:

perl -Mdiagnostics -Mdummy
Can't locate dummy.pm in @INC (@INC contains: /etc/perl /usr/local/lib
+/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/p
+erl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl
+ .).
BEGIN failed--compilation aborted (#1)
    (F) You said to do (or require, or use) a file that couldn't be
    found. Perl looks for the file in all the locations mentioned in @
+INC,
    unless the file name included the full path to the file.  Perhaps 
+you
    need to set the PERL5LIB or PERL5OPT environment variable to say w
+here
    the extra library is, or maybe the script needs to add the library
+ name
    to @INC.  Or maybe you just misspelled the name of the file.  See
    perlfunc/require and lib.

Off-topic?!?

Or how does splain help to find error-msgs close to Can't find function in @INC?
