I can't build pgAgent&pgAdmin3

Hello<br />     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. <br
/>   When I tried to build pgAdmin 1.6.3 under Windows Xp sp2, using VS 2005, I succeeded in building pgaevent, but
failedto do with pgAgent & pgAdmin3.<br />    When I tried to build pgAdmin3, VS says "error PRJ0019: Tools from
'Extractingsubversion repository version'  " and "BSCMAKE: error BK1506 : : No such file or directory" <br />    When I
triedto build pgAgent, it says "can't open .\Debug/pgAgent.pch: No such file or directory" and <br />"BSCMAKE: error
BK1506: : No such file or directory".<br />    What shall I do now? <br />Regards,<br />    Ranc.<br />
