[BioC] Problems loading Rgraphviz package under Windows XP

[Jasmina Bogojeska]

Dear all,

I have problems loading the Rgraphviz package under Windows with  the
newest version of R.

The Windows I am using is Windows XP Professional (Version 2002) Service
Pack 2.

Here is the error message I am getting:
Error in inDL(x, as.logical(local), as.logical(now), ...) :
  unable to load shared library
'C:/PROGRA~1/R/R-27~1.0RC/library/Rgraphviz/libs/Rgraphviz.dll':
  LoadLibrary failure:  The specified module could not be found.


Error : .onLoad failed in 'loadNamespace' for 'Rgraphviz'
Error: package/namespace load failed for 'Rgraphviz'

The version of Bioconductor is 2.2.

And here is the session info:
R version 2.7.0 RC (2008-04-16 r45356)
