Subject ZLIB error when compiling IBO project
Author Roberto Freitas
When Installing IBO and compiling all projects, I've got this error
message on package IBO40VRT_D7 line 73:

[Error] IBO40VRT_D7.dpk(73): Package 'rtl' already contains
unit 'ZLib'

That line 73 is
ZLIB in 'ZLIB.pas';

There is a naive solution - to comment this source line - and it
works, but perpahs it's not the proper solution.
What is the appropriate detailed solution for this?
