Have you tried use strict and use warnigns in your scripts?
Also perl -c script.pl is helpfule and then the perl debugger itself:
perl -d

I'm sure their's thrid party stuff but I never use any, 
the above does plenty for my needs.

Re: PERL debuggers

[Dan Anderson]

I've created a module that I am planning on eventually releasing to CPAN
which provides a good framework for debugging.  Basically you can have
your code report 4 types of warnings: 

INFO
WARNING
ERROR
FATAL_ERROR

You can also assign a "class" to each and turn on or off all of one type
or all of one subclass of one type.  Everything either records to a log
file or prints to STDERR, and I am going to (eventually) add the
capability to e-mail the log of errors to an admin.  (So if you create a
program and your users do something unexpected you can have them send
you a readout of exactly what happened).  And I've got a bunch of other
ideas (i.e. HTML output) that I may implement when I finally manage to
getting around to see if I can put it on CPAN.

It's written in pure perl and GPLed.  e-mail me if you'd like me to send
you over a copy.  It's still being developed though.

Re: PERL debuggers

I'd like to add that it's not a debugger like the one someone else
posted for stepping through your code and setting breakpoints.  It's
designed to allow you to create a log with the state of your script and
what has been done, so that way you can have somebody who is not a
programmer and who is using your script send you the log (because, of
course, most of those type of people can't debug with you over the
phone).  :-D

Certainly not trying to discredit your efforts, just spreading the
log4perl wealth, I have found it incredibly robust while at the same
time being complex enough to handle some intricate tasks.

For more information, be sure to check out the "retire your debugger"
article

Good luck,

No, I love perldebug, I was just wondering if I there were any other "neat

You apppear to have a broad definition of "debugger" that
extends beyond the customary trace/inspect tool into
any device that helps you detect or prevent bugs.  So I
will take the liberty of saying that it was my intention
to enumerate such devices in the book "Perl Debugged" (see
URL below).  Plus, it has cute cartoons :-)

No, it's alot better.  It has a look that is similar to the MSVC or VB
debugging tools and allows you to step into/over, etc.  I don't use it all
the time, but every once in a while it can be useful.  It lets you see what
is happening all in one place.

Unless they have added something - isn't this the same one that
comes with the standard perl release

I will agree with most folks that working stuff in a 'debugger'
tends to be a bit more work than the usual

prinf(...)

types of solutions - but it also saves you the time of putting
them in and taking them out...

No. The Perl Dev Kit contains a graphical debuger.

And then there is the ptkdb : http://world.std.com/~aep/ptkdb/

Both are quite good :-)

To get similar type of debuging "free" you may use Devel::TraceSubs :
