[Lazarus] Error during Lazarus rebuilding 0.9.30

[Frank Church]

I am trying out Lazarus 0.9.30 and on trying to install a component package
I get this error during the installation phase after the package has been
compiled.

 componenttreeview.pas(44,18) Fatal: Can't find unit ComponentTreeView used
by ObjectInspector

The aforementioned file is sitting blissfully in C:\lazarus930\ideintf.

Is it a known issue, or could it have something to do with the package i am
trying to compile: KGridLaz from www.tkweb.eu?
