I cannot install either complete packages (*.lpk) or individual component files (via Add active unit to a package) into Lazarus 0.9.29 fpc 2.4.1. I have done so successfully in earlier versions (0.9.26/2.2.2), but the new version will not accept them on recompiling the packages. Errors such as "Can't find unit Unix used by FileProcs" stop the compilation, even though unit unix.pp appears in the fpc source directory (via subdirectory rtl\Unix). I have tried putting more specific search paths directly to the Unix directory, but it still can't find the unix unit, and won't allow more than one search directory.
It all works OK with the earlier version (and with the same unix.pp file in the same subdirectory), so what am I doing wrong?
