Yes, or on contrary maybe a pure temp directory: in any case we don't 
keep it so that name should not be important. Other details may need to 
be reviewed like runtime dependencies, strip binaries or not (at most a 
couple of MB so probably pointless).

And most important, real testing (I only checked that named loads with 
no error).

I fear side effects of the "--prefix=/install". There is probably a 
better way to change installation path.
