[Lazarus] Revision 28960 Compilation Error

[Dave Coventry]

On Ubuntu 10.10 I've run the following command:

root at SNECCII:/opt# svn co http://svn.freepascal.org/svn/lazarus/trunk lazarus
Checked out revision 28960.

I've got this error:

compileroptions.pp(427,14) Error: There is no method in an ancestor
class to be overridden:
"TCompilerMessagesList.Equals(TObject):Boolean;"
compileroptions.pp(734,39) Fatal: There were 1 errors compiling module, stopping
Fatal: Compilation aborted

Anyone got an idea of what's going on? My root partition is awfully
close to full, but I think I have enough space yet.
