[Lazarus] Can't find package

[Santiago A.]

Hello:

I had installed in my ubuntu 9.10 Lazarus 0.9.28. I finally decided to
upgrade it to 0.9.30.
I removed 0.9.28 to start from scratch, downloaded the deb packages
fpc-2.42 and lazarus-0.9.30 (in big tarballS). 

After several issues with dependences, I managed to install it. Besides, I have removed the $home/.lazarus directory

But now I try to add the package sqlite3laz from the IDE, when I rebuild
it and I get "Can't find unit sqlite3laz". But sqlite3laz.pas is in 
/usr/lib/lazarus/0.9.30/components/sqlite.

I tried to compile the package from menu package/open loaded package, but I get "you don't have permission to write 
on /usr/lib/lazarus directory" or similar. So I have run Lazarus as root and compiled and tried again, now it has 
compiled the package and generated the following files:

/usr/lib/azarus/components/sqlite/lib/i386-linux/gtk2/sqlite3laz.o
/usr/lib/azarus/components/sqlite/lib/i386-linux/gtk2/sqlite3laz.compiled
/usr/lib/azarus/components/sqlite/lib/i386-linux/gtk2/sqlitecomponenteditor.ppu
/usr/lib/azarus/components/sqlite/lib/i386-linux/gtk2/sqlite3laz.ppu
/usr/lib/azarus/components/sqlite/lib/i386-linux/gtk2/sqlitecomponenteditor.o

But when I build lazarus, I get the same result: "Can't find unit sqlite3laz"
any path or macro missing? Any Idea or clue about what's happening?

Regards
Santiago A.
