VS2005 Beta2, devenv.exe command line for a ClearCase bound solution problem

I get the following error:
Package 'Visual Studio Source Control Integration Package' failed to load.

when compiling a ClearCase bound solution from the command line

c:\Solutions>"c:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv.exe"  "c:\Solutions\BasicUtilities.sln"   /Build Debug /out mylog.txt

I have installed VS2005 Beta2, Team System edition, after uninstalling VS2003.
VS2003 was integrated with IBM Rational ClearCase.
I have no problem opening a solution with VS2005 GUI and perform build

If I remove Scc tags from the project, everything builds fine.

Any tip is highly appreciated
