Perlapp and DateTime parsers - NOT!?!?

Hi,

I've spent a day racking my brain trying to use the DateTime
package  
in a perlapp'ed script. Actually, the following absolutely
minimal  
script is enough to make things go awry:

# foo.pl
# compile using: 'perlapp --add DateTime::Locale::en foo.pl'
use DateTime::Format::ISO8601;
__END__

The --add is not enough actually, but enough to illustrate
this, and  
further, there is no list of --add that can salvage the
situation it  
appears to me :-(

BTW, this is using PDK 6.0.2, Build 819 on WinXP (plus some
CPAN work  
to get the appropriate DateTime: stuff set
up).

Trying to run the exe produces this:

The following parameter was passed in the call to  
DateTime::Format::Builder::Parser::create_single_parser but
was not  
listed in the validation options: params

Looks daunting, but figuring it was just a matter of missing
--add  
stuff required I set to work discovering what it might be...

Turns out that no, the 'pluggable' parsers in  
DateTime::Format::Builder::Parser: is not
getting loaded. However,  
after inspecting DateTime::Format::Builder::Parser (.pm),
they are  
loaded dynamically after discovering them using  
Class::Factory::Util...and this is done purely diskbased
from looking  
at INC, and this technique won't work in Perlapp if I
understand  
correctly. Actually, if I put stuff on disk alongside the
exe, the  
code will find it. Not really comfy with this...maybe I
could bind the  
required stuff in the exe, extract it and it will magically 

work...will test that. Still, seems like a messy
workaround...

Any thoughts on this, or any clever trick I have overlooked?

TIA,

So you have worked out what the issue is when I read to the
end. 
Similar situations exist with PDF::API2 and Class:BI. All
you need 
to do is work out what is needed and then you can bind them
to the 
exe in the same way. PerlApp is very good at resolving
dependencies, 
but not infallible.

Well you must have worked out what was necessary when you
said 
further down that you moved some files into the directory
and it all 
worked. Just bind those same files into the exe. Then you
WILL have 
salvaged the situation.

No clever trick, but dynamic loading of plug-ins does cause
issues.
