Perl, Wx, DBI and PAR on Win32 - deployment problems?

[lukeyboy1]

Good afternoon, wise monks. An interesting problem for you - and I don't see any mention of it on the site.

I've an application that looks a bit like this:

#!/c:/perl/bin/perl


use strict;
use DBI;
use Wx;
use myClass;

...blah....

Anyway, It all just works perfectly, when I both run and it build an exe with pp on my machine. This is, of course, the case, since I've lots of perl specific stuff on my machine, and all the paths are set up correctly (etc.)
I'm using the following to build it:

pp -M Wx -M DBI -M myClass -B -o gui.exe foo.pl

I'm also packaging lots of DLLs, and installing them in C:/Winnt/system32 with it, in order to satisfy any requirements, these are:

wxmsw26_stc_gcc_custom.dll
wxmsw26_media_gcc_custom.dll
wxmsw26_html_gcc_custom.dll
wxmsw26_gl_gcc_custom.dll
wxmsw26_core_gcc_custom.dll
wxmsw26_adv_gcc_custom.dll
wxbase26_gcc_custom.dll
mingwm10.dll
perl58.dll

The main problem is that it just doesn't work on other win32 machines when I deploy it(*). I just can't think of other things I need to do, and I was wondering if the monks had any pearls of wisdom to pass on to me?

Thanks!

(*) I'm using the Nullsoft installer to build a proper installer for the application, for the avoidance of doubt!
