Building the py2exe 'advanced' sample (which contains a trivial wx
program)
raises this error (XP SP2, Python 2.5, py2exe CVS version, wxPython
2.7.2 ansi):

c:\sf\py2exe\py2exe\samples\advanced>py25 setup.py py2exe

*** finding dlls needed ***
error: gdiplus.dll: No such file or directory

This is probably what the OP had seen.
py2exe parses the import table of the dlls and pyds it find and tries
recursively to find the dlls needed.  Using the default Windows dll
search
path, IIRC.  Apparently it does not find gdiplus.dll (which may be a bug
in py2exe).

When I run dependencywalker on wxmsw272h_core_vc.dll, dependencywalker
does find gdiplus.dll (but I do not know how, actually).  gdiplus is in
these
directories on my system:

c:\WINDOWS\WinSxS\x86_Microsoft.Windows.GdiPlus_6595b64144ccf1df_1.0.0.0
_x-ww_8d353f13\GdiPlus.dll
c:\WINDOWS\WinSxS\x86_Microsoft.Windows.GdiPlus_6595b64144ccf1df_1.0.260
0.2180_x-ww_522f9f82\GdiPlus.dll

What does the wxPython installer do?  Shouldn't it install gdiplus.dll,
since it is
required by wxPython, install the dll in the c:\Python25 directory? Or
does it only
do this on pre-XP systems?  I guess that py2exe would have found it
there.
