This option may be used any number of times.

Yeah I have meant that it works _even_ if you also have
system-wide installation. No idea what dmd.conf they put into zip
- I never use it.

Unzip, add ...dmd2/linux/bin64 to PATH. Done. (The following is a stupid workaround that may be employed for libs that don't follow the normal naming convention. Phobos shouldn't be one of them but...) But lets say you want to force it to link to a specific lib that is in a lookup path you could use the full filename: -L-l:libphobos2.so
