You just need the right constant in your SaveAs Command: 
use strict;
use Win32::OLE qw(in with);
use Win32::OLE::Const 'Microsoft PowerPoint';

my $filename = 'somehtml.html';
my $PptApp  = Win32::OLE->GetActiveObject('PowerPoint.Application')
        || Win32::OLE->new('PowerPoint.Application', 'Quit'); 
     
  $PptApp->{Visible} = 1;
  my $Presentation = $PptApp->Presentations->Open({Filename=>'somepres
+entation.ppt',
                                                   ReadOnly=>1});
 
   $Presentation->SaveAs({Filename => $myfilename,
                         FileFormat=> ppSaveAsHTML});

Update:I should have put some references in- I found the proper constant using the object viewer in Visual Basic (I added a reference to the PowerPoint libs to a proj). If you DON'T have VB installed, and you are using Active State's install, then I would suggest using their web-based object browser. It's a file named, aptly enough, browser.html, and I found mine in -

c:\perl\html\site\win32\ole\browser
