Perl Mapscript 4.4 Issues

Some perl variables that might be interesting to print out:

$]
~    The version + patchlevel / 1000 of the Perl interpreter.

$^V
~    The revision, version, and subversion of the Perl interpreter,
represented as a string composed of characters with those ordinals.

@INC
	The array @INC contains the list of places that the do EXPR, require,
or use constructs look for their library files.

These should at least tell you that you're running from the right perl
installation.

| Thanks for all the assistance thus far. Is there a script available
that outputs the version & associated compilation of Perl Mapscript
being hit by different processes? I'm getting Perl Mapscript working OK
straight through a browser and Apache cgi, but it's my ArcIMS Emulation
stuff giving me the error outlined below. I'm just wondering if somehow
I've got processes pointing at 2 different installations.

| Rob,
|
| I usually see this error after upgrading and trying to reference a
| member or method that no longer exists.
|>From the error it appears the code may be trying to do something like
| '$variable = $class->{styles}' and styles does not exist under class in
| 4.4 - you're upgrading from 4.0 is my guess.?
| The reply to Steve had nothing to do with alterring mapscript.pm but
| rather that the docs had/have a typo.
