[igraph] Having a problem in installing igraph 0.6

[taraki]

Hi,
I have been trying to install a nightly-build packages of igraph 0.6
without success. It will be very helpful if you could tell me what I
need to do.

The error message that comes up repeatedly is something like this:

"c:\users\...\downloads\python-igraph-0.6\src\arpackobject.h(28) :
C1083: include cannot open the file 'igraph_arpack.h': No such file or
directory
error: command '"C:\Program Files\Microsoft Visual Studio 9.0\VC\BIN
\cl.exe"' failed with exit status 2"

My PC has:
Windows 7, Python 2.6.6, MS Visual Studio 9.0.

The versions I have tried to install were:
  python-igraph_nightly_0.6-2436-20110504.tar.gz
  python-igraph_nightly_0.6-2429-20110502.tar.gz

I am a biginner of Python and igraph but I have a specific need for
using igraph 0.6 instead of the previous versions.
Please let me know if I should provide any other information on this
issue.
Thank you for your attention.
