I guess the build command has some problems with long a list of parameters:
C:\D\dsss\tmp\derelictgl>dsss build
Creating imports for DD-derelict-opengl
derelict\opengl => DD-derelict-opengl

Command c:\D\dsss\bin\rebuild.exe returned with exitcode 1, aborting.
C:\>dsss net install derelictgl

Error: files.tmp: The system cannot find the file specified.
When calling rebuild manually it just says
The input line is too long.
The same operation works on Linux.
