It is not a matter of path, but rather allowing the ports tree to handle properly all kind of library name, right now we have some false limitation and library name collision because we wrongly rely on ldconfig -r. we have lots of patches so convert library names to a format libname.so.asinglenumber, just for the sake of a technical limitation of the ports tree. That is what I m trying to fix. regards, Bapt
