If the package cannot coexist with other packages (because of file conflicts, runtime incompatibilities, etc.), list the other package names in CONFLICTS_INSTALL. Use shell globs like * and ? here. Enumerate package names in there, not port names or origins. Please make sure that CONFLICTS_INSTALL does not match this port's package itself. Otherwise enforcing its installation with FORCE_PKG_REGISTER will no longer work. CONFLICTS_INSTALL check is done after the build stage and prior to the install stage.

If the port cannot be built when other specific ports are already installed, list the other port names in CONFLICTS_BUILD. Use shell globs like * and ? here. Use package names, not port names or origins. CONFLICTS_BUILD check is done prior to the build stage. Build conflicts are not recorded in the resulting package.

If the port cannot be built if a certain port is already installed and the resulting package cannot coexist with the other package, list the other package name in CONFLICTS. use shell globs like * and ? here. Enumerate package names in there, not port names or origins. Please make sure that CONFLICTS does not match this port's package itself. Otherwise enforcing its installation with FORCE_PKG_REGISTER will no longer work. CONFLICTS check is done prior to the build stage and prior to the install stage.
