Problems with linking and Tango

[Uwe Keller]

Hi. 
I am a beginner with D and implemented a solver for SUDOKU puzzles using DMD and Tango. 

When I try to compile the code with rebuild using the following command:

rebuild src/evanescent/apps/sudoku/core/CommandLineInterface.d -O -release -inline -Isrc/ -I../../deescover/src/ -ofbin/sudoku-solver -clean

then I get the following errors by the linker that basically tell me nothing: 

/usr/lib/d/libtango-base-dmd.a(deh2.o): In function `_D4deh213__eh_finddataFPvZPS4deh213DHandlerTable':

Does somebody know what the problem is (something with the Tango Lib include seems not working) and what I can do to resolve it?

Thanks a million in advance!
Uwe.
