I've setup dsss exactly how it is described and added it to the PATH, but it always states: "Failed to determine DSSS' installed prefix".

It's the same problem as here:
http://www.mail-archive.com/digitalmars-d-learn@puremagic.com/msg00291.html

but the solution doesn't work for me.
./dsss --prefix=/home/.../D/dsss/ install
-> Unrecognized argument: --prefix=/home/.../D/dsss/

What am I doing wrong?
