Ambiguous Units Found

[JanRoza]

I wanted to install ZeosLib into Lazaras 0.9.25 RC1 but I get an error message about ambiguous units found.

(http://213.10.59.241/LazAmbiguous.jpg)

The funny thing is that it is the same path found twice, one time via $LazarusDir and one time the full path.

I tried some other packages but I get this error on every package I want to install.
I cannot find those paths anywhere in the options or the sources.
How do I solve a problem like this?
Where do I have to look?
