a problem with mapscript

[Stephen Lime]

Probably a parsing error in the mapfile. Use the shp2img utility to test the
mapfile syntax and see what's wrong. There are error strings exported for
mapscript but I can't remember the syntax at the moment.

The os error ($!) probably could be set elsewhere in the process of loading
the mapfile (eg. opening a symbol or font file) and doesn't necessarily mean
that it can't open the mapfile itself.

I tried this out using the ms_demo mapfile, and did not get an ioctl error, 
yet a file not found error on a RedHat6.2:

[naboo:~/mapscript_test]{170}% pwd
/home/tkralidi/mapscript_test
[naboo:~/mapscript_test]{171}% cat ./test.pl
#!/usr/bin/perl -w

use mapscript;
use strict;

my $map = new mapObj('/home/tkralidi/mapscript_test/demo.map') or die 
"Unable to open mapfile: $!\n";
my $img = $map->draw() or die('Unable to draw map $!');
mapscript::msSaveImage($img, '/tmp/imgfile', $map->{interlace}, 
$map->{transparent});
[naboo:~/mapscript_test]{172}% perl ./test.pl
Unable to open mapfile: No such file or directory
[naboo:~/mapscript_test]{173}%

a run with a -d switch gives me this:

[naboo:~/mapscript_test]{173}% perl -d test.pl

Loading DB routines from perl5db.pl version 1.0402
Emacs support available.

Enter h or `h h' for help.

main::(test.pl:6):      my $map = new 
mapObj('/home/tkralidi/mapscript_test/demo.map') or die "Unable to ope
n mapfile: $!\n";
  DB<1> next
Exiting eval via next at (eval 7) line 2.
        eval '($@, $!, $^E, $,, $/, $\\, $^W) = @saved;package main; $^D = 
$^D | $DB::db_stop;
next;

;' called at /usr/lib/perl5/5.00503/perl5db.pl line 1239
        DB::eval called at /usr/lib/perl5/5.00503/perl5db.pl line 1133
        DB::DB called at test.pl line 6

What gives here?
