You meant,

I still think using ocamlbuild with installed libraries/modules is a  
little bit problematic. If we have to do it that way [1] we are hard- 
coding the location of the library in the plugin which doesn't feel  
right.

For me there should be (1) a way of defining the dependency on a  
module/library (hopefully without needing a plugin) and (2) a way of  
defining its location (-I). These two aspects should be decoupled.  
This makes it easier to drive the installation process in build  
scripts by using environment variables, i.e. I just need
to specify the location of the module/library I depend on via a  
suitable -I $DEPDIR to compile the sources.

Best,

Daniel
