I have removed indy form lazarus, deleted indy directory, rebuild lazarus.
Then I have copied a new Indy directory, compiled the package, installed it.
Now, I reopen my project, try to compile and
I GET EXACTLY THE SAME ERROR !!!
/Developer/lazarus/components/indy-10.2.0.3/fpc/IdFTP.pas(705,17) Fatal: Can't find unit IdFtpCommon used by IdFTP
