Ok, I'm pretty sure there is a bug here.
Steps to reproduce.

rm ~/.lazarus
cp -a lazarus.clean lazarus.a
cd lazarus.a
make
lazarus
<here I simply set the ide build options to all and re-build the IDE from within lazarus. I need to 
do this so lazarus will create an ~/.lazarus/idemake.cfg file>
cd ..
cp -a lazarus.clean lazarus.b
cd lazarus.b
make all idepkg

lazarus.clean is a pristine svn checkout.

I have to do the lazarus.a build / run to recreate my ~/.lazarus directory. No packages installed, 
no pre-existing configuration.
