you should make yourself happy with that, since it's almost the only way
it can possibly work. The IDE must be able to locate design time
packages through the library path, and the packages must in turn be able
to locate run time (dcp and) bpl files though standard system calls
(LoadLibrary). So, the directory in which those files reside must be in
the system path. That's the reason why Delphi's bpl files are installed
under SYSTEM(32) directory.
If you don't want to add $Delphi\Projects\Bpl to the system path, then
change the bpl and dcp output path of IBO packages to SYSTEM(32) and
then recompile, but I must say that $Delphi\Projects\Bpl is a well
accepted standard by now.
Ciao
