Qwt plugins in QtDesigner are absent by default

[GoogleCodeExporter]

Hi Everyone. I've installed Python(x,y) 2.6.6.0, in windows XP SP3 (32-bit) and 
7 64-bit.

The problem is simple, and shows up on both installs: In the QtDesigner bundled 
with Python(x,y), the widgets for Qwt are absent. A check in "About plugins..." 
reveals:

Failed plugins:
Cannot load library: 
C:\Python26\Lib\site-packages\PyQt4\plugins\designer\qwt_designer_plugin5.dll: 
Unable to the specified module

But qwt_designer_plugin5.dll does exist at the indicated path. Looking around 
the Internet I learned qwt_designer_plugin5.dll invokes qwt5.dll, which is 
generated by the compilation of Qwt from sources, but I didn't find the file 
anywhere within the pythonxy or Python26 folder trees. It would seem to me this 
file is not packaged in the installer. I think it is necessary to include it, 
in order to provide a full and convenient PyQwt design workflow.

Details of my installations:
I've selected all of the plugins save the medical ones, in case it helps. The 
directories I've chosen are:
- For Python 2.6 itself, the default (i.e. C:\Python26)
- For python(x,y), C:\data\progs\pythonxy
-  All subsequent content (docs, examples, etc.) are also placed under this 
folder.
I think I've installed for "Current user only". Before installing, I cleaned my 
computer from any previous Python installs, by running their uninstallers, 
manually removing leftover folders and running CCleaner to purge the registry.

I've mistyped the error message. It is as follows:
Failed plugins:
Cannot load library: 
C:\Python26\Lib\site-packages\PyQt4\plugins\designer\qwt_designer_plugin5.dll: 
The specified module could not be found.

Thanks.

Typically this is caused by having some older Qt DLLs in the path.

If still applicable, please check the above and re-open the issue.
