No, it does not help.

But keeping sources and compiled units folder apart, in fact, seems to 
resolve the issue. I followed the example of LazReport which consists of 
several packages as well, but every package has its own source and 
destination folders.

I still wonder why the IDE compiles correctly with TAChart - it 
constists of the main package TAChartLazarusPkg and several dependent 
packages such as TAChartWMF or TAChartFPVectorial. None of these has 
"Add package unit to uses section" unchecked. All sources and packages 
are in the same source folder and compile into the same destination 
folder. I never had any compilation issues with TAChart.
