Perl CGI: No such file and directory: Yet file exists?
This technically a homework problem but I just need help solving this strange issue. The code is kinda long, I tried posted only the relevant parts.

1. The problem statement, all variables and given/known data:

I receive this error:

Code:
got error No such file or directory (2)

at:
Code:
open(GRADES,"<<$grades") or die "got error $! (".($!+0).")\n";

line 49 in CreateExam.pm called from submit.cgi, linked below.

2. Relevant commands, code, scripts, algorithms:
submit.cgi:
Code:
	my $check = CreateExam->new("/var/www/roger/homeworks/hw13/exam4.txt","/var/www/roger/homeworks/hw13/answers4.txt","/var/www/roger/homeworks/hw13/grades4.txt",$pathroot);


CreateExam.pm:

Code:
sub new {
	my ($class,$file,$answers,$grades,$script) = @_;
	#print "<p>in new: file: $file, grades: $grades</p>\n";
	return bless {'file'=>$file,'answers'=>$answers,'gradefile'=>$grades,'script'=>$script},$class;
}

Code:
my $grades = $self->{'gradefile'};
open(GRADES,"<<$grades") or die "got error $! (".($!+0).")\n";

3. The attempts at a solution (include all code and scripts):

I tried all of those recommendations: I remove any whitespace, I put in a check for any nonprintable characters, I hard-coded the path.

To make sure it wasn't a permissions issue, I installed suExec-custom for debian, all cgi scripts run under my UID, that didn't help.

I'm running this on debian with Apache

locale::codes::langvar

Locale::Codes::LangVar(3pm)				 Perl Programmers Reference Guide			       Locale::Codes::LangVar(3pm)

NAME

       Locale::Codes::LangVar - standard codes for language variation identification

SYNOPSIS

	  use Locale::Codes::LangVar;

	  $lvar = code2langvar('acm');		       # $lvar gets 'Mesopotamian Arabic'
	  $code = langvar2code('Mesopotamian Arabic'); # $code gets 'acm'

	  @codes   = all_langvar_codes();
	  @names   = all_langvar_names();

DESCRIPTION

       The "Locale::Codes::LangVar" module provides access to standard codes used for identifying language variations, such as those as defined in
       the IANA language registry.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default IANA language
       registry codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying language variations. A code set may be specified using either a name, or
       a constant that is automatically exported by this module.

       For example, the two are equivalent:

	  $lvar = code2langvar('en','alpha-2');
	  $lvar = code2langvar('en',LOCALE_CODE_ALPHA_2);

       The codesets currently supported are:

       alpha
	   This is the set of alphanumeric codes from the IANA language registry, such as 'arevela' for Eastern Armenian.

	   This code set is identified with the symbol "LOCALE_LANGVAR_ALPHA".

	   This is the default code set.

ROUTINES

       code2langvar ( CODE [,CODESET] )
       langvar2code ( NAME [,CODESET] )
       langvar_code2code ( CODE ,CODESET ,CODESET2 )
       all_langvar_codes ( [CODESET] )
       all_langvar_names ( [CODESET] )
       Locale::Codes::LangVar::rename_langvar  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Codes::LangVar::add_langvar  ( CODE ,NAME [,CODESET] )
       Locale::Codes::LangVar::delete_langvar  ( CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_alias  ( NAME ,NEW_NAME )
       Locale::Codes::LangVar::delete_langvar_alias  ( NAME )
       Locale::Codes::LangVar::rename_langvar_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::add_langvar_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Codes::LangVar::delete_langvar_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes::API man page.
