CPAN-testers reports some failures[0] for a module I've written. I want
to fix these, but I must admit I'm a bit stumped. I can't see why this
should fail.

Any pointers?

First, when I asked a similar question on PerlMonks, the consensus was
the CPANPLUS often handled dependencies incorrectly, and that warnings
about dependencies should be ignored:
http://www.perlmonks.org/index.pl?node_id=372922
The error messages for your module don't look like dependency
problems, though.
One useful thing is to see how the environments where it's failing are
different from yours. For example, a different version of Perl, a
different endianness if you're doing the sorts of things that depend
on that, etc. It's straightforward to install a different version of
Perl in a temporary location and see how your module works with it;
finding a machine of a different endianness might be a little
trickier.
Another useful thing is to see what it's dying from (often undefined
or empty variables, it looks like) and add assert-style checks for
that in various places in your program. That way if it dies at least
you'll know where. Something like:
defined($a) or die "$a not defined";
inserted in appropriate places would tell you when a variable first
became undefined, for example.

I think they might be. The module depends on the latest version of a
different module. If instead an earlier version of this module was used
this problem could well occur, I believe.

I've talked to one of the testers where the tests failed, and he can not
reproduce it. I'm starting to suspect the module is actually ok.

The obvious thing that springs to mind is the possibility that you are
not specifying the correct minimum versions in the prerequisites but
having looked at the source of this module I can't convince myself
that this is the case.
Note: I think module numbers are compared as pure numbers. This means
that 0.2.0 and 0.2.3 are noor distinct.

I've been in contact with one of the testers that had a failure. He said
he now cannot reproduce it, but that the first time he tested it some
dependency problems were reported. The module depends on the latest
version of a different module I've written, and if that was not
installed I can well imagine that this error would occur.

I was of the impression that this would be fine, as long as the version
numbers where quoted (but maybe I've missinterpreted
http://search.cpan.org/~jpeacock/version-0.41/lib/version.pm#Quoted_Versions
?).
