"Required package rtl not found" when building with Hudson

Question

I am trying to get Hudson to work with my Delphi project. I am using the following batch file to build my project (as suggested in this blog post):

call "C:\Program Files\Embarcadero\RAD Studio\8.0\bin\rsvars.bat"
msbuild /p:Win32LibraryPath="$(BDS)\lib;$(BDS)\lib\win32\release;$(BDS)\lib\win32\debug;$(BDSUSERDIR)\Imports;$(BDS)\Imports;$(BDSCOMMONDIR)\Dcp;$(BDS)\include;" /t:build /p:config=Debug /verbosity:detailed "MyProject\src\MyProject.dproj"
if errorlevel 1 exit 1

I always end up with the error

Embarcadero Delphi for Win32 compiler version 22.0
Copyright (c) 1983,2010 Embarcadero Technologies, Inc.
Fatal: E2202 Required package 'rtl' not found

I don't understand this as rtl.dcp is in "$(BDS)\lib\win32\release" which is on the library path. I am using runtime packages by the way.

Any hints what I can do to solve this?

Edit It seems that the paths do not end up in the command line, which looks something like (after removing project-specific paths):

C:\Program Files\Embarcadero\RAD Studio\8.0\bin\dcc32.exe -$O- -$W+ --inline:off -$A4 -$R+ -$Q+ --doc --no-config -B -LUrtl;vcl;ReportingR;ComponentsR -Q -AWinTypes=Windows;WinProcs=Windows;DbiTypes=BDE;DbiProcs=BDE;DbiErrs=BDE -DDEBUG;CONSTRAINT_CHECKING;_VER6;EUREKALOG_VER6;EurekaLog -V -VN -GD --drc -W-SYMBOL_DEPRECATED -W-SYMBOL_PLATFORM -W-UNIT_PLATFORM -W-UNIT_DEPRECATED   Myproject.dpr   

Solution

I found the answer in a comment to the original blog post. It turns out that in Delphi XE they changed the name of the Win32LibraryPath property to DelphiWin32LibraryPath. Changing the batch script accordingly fixes the issue.
