[Catalyst] System call problem

Hi all,

My Catalyst application uses an external Perl module that needs to call 
an external application using the Perl system() command. This Perl 
module works fine on its own (no error message when the external app is 
called). However, whenever used from within my Catalyst application 
thtough the Catalyst test server, the return status of the system() call 
is always -1 (failure, success is 0), even though the call seems to be 
executing just fine (valid output files are produced).

This is the system call:
>       system(@formatdb_cmd) == 0 or die("Could not run command: 
> @formatdb_cmd\n$?");
I tried to implement the system call with IPC::Run, but it just did the 
>       IPC::Run::run(\@formatdb_cmd) or die "Could not run command: 
> @formatdb_cmd\n$?";
Any idea what is going wrong? Do I need to do something in Catalyst? 
Should I just ignore the system() return status  (but then I would miss 
real execution errors)?
