I can't build pgAgent&pgAdmin3

["rancpine cui" <rancpine(at)gmail(dot)com>]

Hello
     I've installe PostgreSQL 8.1 into the default location from the official PostgreSQL installer (pgInstaller). And in my $BUILD_ROOT/pgadmin3-deps/ ,  I've already got wxWidgets, libxml2, libxslt, iconv and zlib.
    When I tried to build pgAdmin 1.6.3 under Windows Xp sp2, using VS 2005, I succeeded in building pgaevent, but failed to do with pgAgent & pgAdmin3.
    When I tried to build pgAdmin3, VS says "error PRJ0019: Tools from 'Extracting subversion repository version'  " and "BSCMAKE: error BK1506 : : No such file or directory"
    When I tried to build pgAgent, it says "can't open .\Debug/pgAgent.pch: No such file or directory" and 
"BSCMAKE: error BK1506 : : No such file or directory".
    What shall I do now?
Regards,
    Ranc.
