I got PowerPDF from CCR project in http://sourceforge.net/projects/lazarus-ccr/ I opened the file pack_powerpdf.lpk and clicked in Install. The IDE said "Lazarus will be rebuild... YES?" Yes... and the build started. Sometime later I received the message: "Can't found the file componenttreeview.pas" (?) But this file was compile before and is part of IDE.
So, one more time, I just clicked in Tools>Build Lazarus and now it works. The components of PowerPDF are in the palette.
What's happend? This is a bug on compile packages?
Thanks,
Marcos Douglas
