Fatal Error: Unit Idxxx was compiled with a different version of System.RTLVersi

Hello,

I just installed a fresh new Delphi 6 with update 2 and RTL3. I downloaded
Indy 10.0.85 Source and compiled it. But I cannot use any of the components
because if I put any of them on a form in a new application and try to
compile I get the error in Subject.

I have to say I have not installed Indy with Delphi 6 and I have removed all
idxxx.dcu from Lib\Debug dirs, so there should be no other version of Indy
on the computer.

Can anyone help me resolve this issue?

Thanks

Tom Hagen
