I tryed installing using the binary packages on both the original (XP)
system and a different one (running Vista x64). The install ran fine,
but when starting tahoe it fails with an ImportError - "The specified
procedure could not be found" in pycryptopp/publickey/rsa.pyd

I've tryed runing it in Dependency Walker (a tool for windows that
shows DLL dependencies) but it doesn't show anythong usefull:

00:00:08.844: LoadLibraryExA("C:\Python26\lib\site-packages\pycryptopp-0.5.12-py2.6-win32.egg\pycryptopp\publickey\rsa.pyd",

0x00000000, LOAD_WITH_ALTERED_SEARCH_PATH) returned NULL by thread 1.
Error:     (127).

(This computer runs a Hebrew localised version of windows and DW
doesn't show the errors correctly, error 127 is "The specified
procedure could not be found")

I've uploaded the whole log from Dependency Walker here
http://testgrid.allmydata.org:3567/file/URI%3ACHK%3Ablb5mtf4qncuxx6thy7mhwodo4%3Az6f3cycd7tulxzjx6denq25rl3vx5lerv53imgzcvyedu22heqoq%3A3%3A10%3A98758/@@named=/pycryptopp%20dll%20import%20fail.txt

I then tried to build pycryptopp from sources, i've started with
0.5.13 (from pypi.python.org) using MS Visual Studio 2008 Express - it
failed with:

_pycryptoppmodule.obj : error LNK2019: unresolved external symbol
"void __cdecl init_sha256(struct _object *)"
(?init_sha256@@YAXPAU_object@@@Z) referenced in function
_init_pycryptopp

Then i tryed compiling the 0.5.12 version (also from PYPI) and it
built without problems and tahoe worked fine using it.

This is on the original XP machine, i'll try runing it on the other
Vista x64 one with the pycryptopp i built later today.

I've also uploaded the working pycryptopp-0.5.12-py2.6-win32.egg if
anyone is interested:
