The unitdir specifies the path where .ppu or when .ppu is not found the
.pas/.pp are searched. sourcedir is only used for the Makefile and never
passed to the compiler. objdir is only needed for external .o files.

The following should be enough:

[compiler]
options=-S2 -k-L/usr/local/lib -O2
unitdir=./src
targetdir=./obj
